Availability1977–2008

Print Gocco (プリントゴッコ, Purinto Gokko) was a compact, self-contained card printing system developed by Riso Kagaku Corporation and first sold in 1977. Print Gocco achieved significant success and sold over 10 million units cumulatively before production ceased in 2008.[1]

The system was developed for the Japanese custom of sending New Year's Day postcards (年賀状, nengajō) to friends and relatives.

Print Gocco's name was derived from the Japanese word gokko (ごっこ), loosely translated as make-believe play. The name and toy-like design of Print Gocco stem from Riso Kagaku president Noboru Hayama's belief in the importance of play. Hayama stated, "make-believe play is a source of intellectual education and its spirit is... an important national heritage. Therefore, I decided to use the word 'Gocco' as a part of this product name."[2]

Basic operation procedures

[edit]

The Print Gocco process was a variant of screen printing; Print Gocco housed both the screen-making and screen-printing elements within one compact footprint with a hinged plastic frame.

The materials included proprietary blank screens, consisting of thin layer of thermoplastic bonded to a mesh, held in a cardboard frame and covered with transparent film.[3]

Making a master screen

[edit]

Print Gocco screens are constructed of a cardboard frame sandwiched between a thin thermoplastic sheet and a perforated mesh.

Artwork is prepared on a card in carbon-based medium.

To produce a master screen, the user places their original card underneath the mesh. Flash bulbs are inserted into the lamp housing and positioned over the artwork. When the flashbulbs fire, the heat from these bulbs is absorbed by the carbon, melting minute holes in the thermoplastic sheet where direct contact with carbon is made, permanently inscribing the original art into the screen and forming a stencil: the finished master screen. This screen is then immediately ready for use.

Applying ink and printing

[edit]

With the master screen created, the user can apply ink to its surface. This ink is pushed through the screen to create prints. Unlike in screen printing, the ink is stamped onto the printing medium, rather than being squeegeed across it. This method allows the user to apply different colors of ink in different areas of the screen to produce a multi-color printed image. Alternatively, the user can create multiple master screens for different colors. Once the master screen are prepared and ink applied, the user can begin printing. Cards are inserted onto a pad beneath the master screen. By pushing down on the Print Gocco unit, the inked master screen could then be stamped onto many cards, one at a time.

Decline and discontinuation

[edit]

As personal computers and email became increasingly popular throughout the 1990s, the Japanese market for physical New Year's postcards saw considerable loss.[4] In December 2005, Riso Kagaku Corporation announced it would end production of the Print Gocco system due to low sales. A spokesperson for the company stated that "[Print Gocco] sales were essentially a rounding error to a multinational with revenues in the hundreds of millions of dollars."[5] Riso Kagaku Corporation would continue to manufacture Print Gocco screens, inks and other supplies for the system. In the states, an Internet campaign was started under the domain savegocco.com to find a new home for the product.

As of June 2007, Riso Kagaku Corporation announced increased interest in Print Gocco in Japan, and had resumed production of several lines of Print Gocco units and they were available in Japan and through limited import retail stores in the United States.[6][7] Despite this interest, sales did not recover.

On May 30, 2008, Riso Kagaku Corporation announced that it would stop manufacturing and shipping Print Gocco printers in June 2008. Sales had plummeted, dwindling to a mere one percent of their peak volume in the 1990s.[1] It blamed the sharp decline in demand for its printers on the increase in use of home printers.[8] It was to continue producing consumable supplies for the printers.[1]

On December 28, 2012, Riso Kagaku Corporation announced that due to declining sales of Print Gocco supplies, it would permanently discontinue all manufacturing related to Print Gocco.[9]

View on Grokipedia
from Grokipedia
Print Gocco is a compact, user-friendly system developed by the Japanese company Riso Kagaku Corporation, allowing individuals to produce custom color prints on materials such as paper, cards, fabric, and ceramics through a thermal imaging process that creates reusable stencils from original artwork. Launched in September 1977 with the model Print Gocco B6—a personal card printer targeted at home users for creating items like New Year's greetings—the system quickly gained popularity in for its accessibility and playful approach to printing, often described as "make-believe play" in its name. By the late and early , it had become a staple, with cumulative sales exceeding 10 million units and peaking at approximately 15.2 billion yen in revenue (including supplies) for the fiscal year ending March 1994; by 1990, about one-third of Japanese households owned one. The system's success stemmed from its integration of technology with light-sensitive master foils, making duplication simple without specialized skills, and it was even recognized internationally, with a B6 model donated to the Edison Museum in the United States in April 1979. The printing process begins with preparing artwork—such as a photocopy, print, or hand-drawn design using carbon-based pens—placed on the device's pad table, covered by a light-sensitive Print Master (a screen coated with material in a frame), and exposed to a stroboscopic flash from single-use bulbs that melt the coating to form the . is then applied to the exposed areas of the master, which is inserted into the printer unit (powered by two AA batteries), and prints are made by pressing the lid to transfer the image onto the substrate in a single pass, yielding vibrant, screen-print-like results suitable for small runs. Later models, such as the PG-5, expanded capabilities to include multi-color printing and applications on ceramics, while maintaining a portable, all-in-one design that combined exposure, inking, and pressing functions. Demand for Print Gocco waned in the late 1990s due to the rise of personal computers and alternatives, leading Riso Kagaku to announce the discontinuation of shipments in June 2008, though supplies like inks were to remain available initially; by the ending 2008, it accounted for less than 1% of the company's 92.6 billion yen in group sales. Despite its end of production, the system endures as a favorite among artists, makers, and print enthusiasts worldwide for its tactile, low-tech charm, inspiring revival efforts and communities dedicated to sourcing rare consumables like flashbulbs and masters.

History

Development and invention

Print Gocco was invented by Noboru Hayama, the founder and president of Riso Kagaku Corporation, during the mid-1970s as a means to bring professional-level capabilities into the . Hayama drew inspiration from the Japanese concept of "gokko," a form of make-believe play among children that fosters learning and creativity, which he viewed as a vital educational tool and . He chose the name "Gocco" to embody this philosophy, emphasizing playful yet educational engagement with printing technology. Riso Kagaku Corporation launched the first Print Gocco model, the B6, in September 1977, specifically targeting the Japanese tradition of creating personalized New Year's postcards known as nengajō. This timing aligned with the seasonal demand for custom greetings, allowing families to produce their own cards without relying on commercial services. The early design prioritized ease of use for amateurs, enabling small-batch, multi-color prints in a compact format suitable for household settings. The core innovation of Print Gocco lay in adapting traditional screen printing into a self-contained, user-friendly system that employed disposable flash bulbs to thermally expose and create a master screen from an original image. This process eliminated the need for darkrooms or complex equipment, making high-resolution stencil masters accessible at home. A key patent supporting this technology, US Patent 4,128,057, filed on March 12, 1976, and issued on December 5, 1978, described a stencil paper assembly invented by Hayama and Yoshio Tsuji, featuring an ink-impermeable sheet and stencil sheet that held ink securely for multiple prints without smearing.

Launch and popularity

Print Gocco was introduced to the market in September 1977 by Riso Kagaku Corporation as a compact printing system designed for personal card production. The device quickly gained traction, recording explosive sales shortly after its release and becoming a major hit by the end of the year, appealing to both children and adults for its simplicity and accessibility. During the and , Print Gocco reached the height of its popularity in , with cumulative sales exceeding 10 million units by the time production ended in 2008. This surge was largely fueled by the growing demand for custom nengajō, or New Year's greeting cards, which the system enabled households to create with vibrant, personalized designs. Its ease of use transformed it into a staple household tool for seasonal printing, leading to noticeable annual sales spikes in the lead-up to New Year's celebrations. While Print Gocco dominated the Japanese market as a cultural phenomenon for DIY printing, it also sparked initial international interest, such as a donation of the B6 model to the Edison Museum in the United States in 1979. However, its primary success remained rooted in Japan's embrace of affordable, creative home printing for personal expression.

Design and components

Main components

The Print Gocco system centers on a compact, hinged frame that serves as the primary hardware unit, integrating a built-in for exposing and melting the printing master. This frame, typically constructed from durable for lightweight portability, clamps the screen in place and facilitates the process through a simple pressing mechanism, allowing users to produce prints on various surfaces like or fabric. The emphasizes ease of use, with the entire unit sized for operation; for instance, the B6 model measures approximately 20 cm by 15 cm, enabling it to fit in small spaces or be transported easily. Key supplies include blank screens composed of a film layered over a fine fabric, which captures the during exposure and forms the reusable for up to several hundred impressions. Single-use flash bulbs, resembling old camera flashes and filled with , provide the intense heat needed to selectively melt the thermoplastic coating on the screen, creating open areas for ink passage where the is present. Specialized are water-based and quick-drying, formulated for compatibility with the system's and available in colors suited for , fabric, or ceramics, ensuring clean separation between layers in multi-color prints. Accessories essential to the system comprise ink trays for evenly distributing and storing the viscous inks during application, rubber squeegees for spreading across the screen with controlled , and carbon-based used to prepare artwork by mirroring designs from originals like photocopies or drawings for accurate exposure alignment. These elements, often included in starter kits, support the system's self-contained nature without requiring additional equipment.

Models and variations

The Print Gocco line was inaugurated with the B6 model in September 1977 by Riso Kagaku Corporation, designed as a compact system for single-color on B6-sized , equivalent to standard Japanese postcards. Subsequent B6-sized models, such as the PG-5 (), PG-10, PG-10 Super, and PG-11 (), incorporated design upgrades including improved lamp housings for better exposure efficiency and adjustable print beds for precise registration, supporting multi-color through the use of additional master screens for layered applications. Larger variations like the B5 and PG Arts models expanded the print area to 152 mm by 222 mm while maintaining similar ease-of-use features, such as refined pressing mechanisms, though the core portable format persisted without drastic size changes. Specialized were also produced for educational and artistic purposes, often including tailored supplies for creative or instructional settings, though production of all models ceased in 2008 amid declining demand.

Operation

Creating the master screen

The process of creating a master screen in Print Gocco begins with artwork preparation, where users draw designs directly on using carbon-based pens (such as RISO carbon pens) containing heat-sensitive carbon material for thermal transfer. This step allows for custom illustrations or the adaptation of existing designs, with the carbon layer acting as the key element that will interact with the system's heat source during exposure. Photocopies or prints on carbon-rich can also serve as artwork, but hand-drawn originals provide precise control for detailed stencils. Once the artwork is ready, it is placed face-up on the pad table and covered by the blank master screen (with the emulsion side facing down), which consists of a mesh coated with a emulsion. The assembly is positioned within the Gocco unit's exposure stage, often with a blue filter to enhance contrast, and secured under the lamp . Flash bulbs—typically 2 to 4 depending on screen size—are inserted and fired by pressing down on the , generating intense heat that is absorbed by the carbon in the artwork, melting the emulsion in the image areas to create openings while leaving the non-image areas coated and impermeable, forming the . The exposure lasts approximately 1 to 2 seconds per bulb, with larger designs requiring multiple sequential flashes to cover the full area evenly. A single-color master screen produced this way is reusable for approximately 100 prints before re-inking (and longer with ), depending on the type and conditions. For multi-color prints, separate master screens must be created for each color layer, with precise alignment marks ensuring registration across screens. To achieve consistent results, users must ensure even exposure by applying firm, steady during flashing and avoiding moisture on the artwork, which can cause patchy hardening of the . Incomplete stencils often result from insufficient carbon or uneven heat distribution, which can be mitigated by excess carbon from the artwork beforehand or using on minor defects post-exposure.

Inking and printing

After the master screen has been created, the inking process begins by removing the print master from its protective plastic flap and applying a small amount of - or water-based directly over the exposed design areas on the screen. Ink blocking material, such as strips, is often applied around the design edges to contain the ink and prevent spreading or bleeding during . The plastic flap is then replaced over the inked screen to protect it, and the master is reinserted into the printing unit of the Gocco machine, ensuring proper alignment with the guides. The printing cycle involves placing a sheet of paper or cardstock on the machine's ink pad table, which provides a soft, yielding surface for even pressure. The hinged lid is lowered firmly onto the paper using hand pressure from the palms or fingers until the ink transfer stops spreading, typically taking a few seconds per impression. The lid is then lifted to reveal the printed sheet, which is removed and set aside to dry; 2-3 initial test prints on scrap paper are recommended to establish consistent ink flow and avoid faint or uneven results. This cycle can be repeated, with the same master supporting small runs of 1-50 copies before requiring re-inking to maintain quality. For multi-color prints, separate master screens are prepared for each color layer, with designs aligned using built-in registration marks on the machine's guides to ensure accurate overlay. Ink blocking is applied between color areas on a single screen if using fewer masters, preventing mixing during sequential impressions. Each color is printed in turn, building up the image layer by layer on the substrate. The resulting prints exhibit vibrant colors and sharp details, resembling professional screen-printed results suitable for cards, , or artwork on absorbent papers and cardstocks. The process yields high-quality output for limited editions, with adjustments to pressure and ink quantity optimizing coverage without smudging or patchiness.

Cultural significance

Use in Japan

In Japan, Print Gocco found its primary application in the creation of custom nengajō, the traditional New Year's greeting cards that families designed and printed to send personalized messages of goodwill and gratitude to relatives and friends. Developed by Riso Kagaku Corporation in 1977 as a compact home printing system, it allowed users to produce multi-colored, high-quality cards using simple screen-printing techniques, making the annual ritual more accessible and creative without requiring professional equipment. This aligned seamlessly with Japan's longstanding nengajō custom, where postcards bearing zodiac motifs and seasonal wishes are exchanged nationwide, peaking at over 4.45 billion cards sent in 2004 before the digital era's rise contributed to a decline. Enthusiasts continue to use vintage Print Gocco machines for nengajō as recently as 2025. Beyond nengajō, Print Gocco saw broader adoption during the 1980s and 1990s for school projects, where it served as an educational tool to teach children about communication, , and hands-on creativity through activities like crafting holiday cards or simple illustrations. Hobbyists embraced it for personal art endeavors, producing custom prints and zines that fostered a DIY culture of expression, while small businesses utilized it for affordable labeling and promotional materials, enabling low-cost production runs without industrial setups. Its child-friendly design and ease of use further extended to household hobbies, reinforcing its role in everyday creative pursuits. The system's social impact was profound, with over 10 million units sold by the time production ended in , suggesting adoption in a significant portion of Japanese households for seasonal and ongoing rituals. By democratizing printing, Print Gocco promoted family bonding through collaborative card-making sessions and encouraged broader creativity, reflecting post-war Japan's emphasis on accessible tools for personal and communal expression. This integration into daily life and traditions underscored its cultural embedding, particularly in nurturing interpersonal connections via tangible, handmade communications before the shift to digital alternatives.

International adoption

Print Gocco gained traction outside during the 1990s and 2000s, particularly in the , , and , where it was introduced through specialty import shops and burgeoning online DIY printing forums. In the , retailers like imported kits directly from , making the system accessible to hobbyists despite its initial obscurity. Australian suppliers such as NEHOC stocked complete systems and accessories, facilitating adoption among local print enthusiasts. In the UK, early availability came via art supply channels, with organizations like Fine Printmakers offering introductory workshops to demystify the process. The system's appeal fostered dedicated communities among artists, zine makers, and crafters, who valued its compact design for producing small runs of stickers, posters, and limited-edition artwork without the need for large-scale equipment. In the , Jill Bliss incorporated Print Gocco into her Blissen line, creating whimsical taxidermy-themed cards and greeting sets; she further amplified its by launching SaveGocco.com in 2005, which gathered signatures from over 1,000 international users protesting the impending discontinuation. Australian producers, such as the Bizoo collective, used the printer for and arts publications, integrating it into touring demonstrations to engage DIY creators. Artist Cat Rabbit showcased Gocco-printed editions of her embroidered illustrations in exhibitions, highlighting its role in blending craft and . In , printmaker Xtina Lamb has taught hands-on sessions at Medway Fine Printmakers, enabling participants to produce up to 300 postcard-sized editions per screen. A primary challenge for international users was the dependence on Japan-sourced supplies, including inks, screens, and flash bulbs, which prompted the development of networks for trading surplus materials and sharing repair techniques through online tutorials and enthusiast exchanges. These communities often relied on forums and import vendors to mitigate shortages, as domestic alternatives were limited. Following the 2008 production halt, Print Gocco's global niche has endured via second-hand marketplaces like , where vintage units and remaining stock circulate among collectors, alongside ongoing workshops in places like Australia's Midland Junction Arts Centre that teach multi-color techniques to new generations of printmakers. As of 2025, revival efforts continue, including the Homemade Riso + Gocco Revival workshop in . This dedicated following underscores its enduring value in accessible, tactile printing for creative subcultures.

Decline and discontinuation

Reasons for decline

The decline of Print Gocco began in the as the rise of home computers and inkjet printers provided more convenient alternatives for creating personalized greeting cards, eroding the demand for manual screen-printing systems like Gocco. These digital tools allowed users to and print cards directly from software, bypassing the need for Gocco's specialized exposure and inking process, which contributed to a sharp drop in sales within the Japanese market. A key factor was the waning popularity of traditional nengajō (New Year's cards) in , where Gocco had been particularly popular for custom printing. Digital alternatives, such as greetings and online services, accelerated this shift, with nengajō deliveries falling to approximately 743 million cards on January 1, 2024—a nearly 16% decrease from approximately 884 million in 2023—and further to about 491 million on January 1, 2025, a 33% drop from 2024; per-person card sending had already dropped from a peak of 35 in 2003 to 16 in 2021, with average cards received per household declining to 15.4 in 2024 and 10.3 in 2025. Market saturation after the boom, combined with these cultural changes, further reduced the appeal of Gocco for seasonal card-making. Economic pressures also played a role, as Gocco's supplies—including flash bulbs and specialized inks—proved costly compared to the low ongoing expenses of and . By the early , Riso Kagaku reported falling revenues from Gocco, leading to the decision to halt production amid persistently low demand. Despite cumulative sales exceeding 10 million units since its 1977 launch, these factors marked the end of widespread adoption.

Production end and legacy

In December 2005, Riso Kagaku Corporation announced the cessation of Print Gocco printer production, citing low sales amid the rise of digital alternatives. The company initially intended to maintain supply production for existing users, reflecting its commitment to the product's legacy despite shifting market demands. On May 30, 2008, Riso Kagaku issued a further announcement that sales of the Print Gocco main body would end on June 30, 2008, effectively concluding the system's commercial lifecycle after 31 years. Supplies such as inks, screens, and flash bulbs continued to be manufactured temporarily, but all production ceased on December 28, 2012, as demand had fully evaporated. Efforts to revive the product emerged in 2006, when international enthusiasts launched the savegocco.com campaign, petitioning Riso Kagaku to reconsider discontinuation and sustain the system for global hobbyists and artists. Despite gathering support from creative communities, the initiative failed to alter the company's decision, underscoring the irreversible shift toward technologies. Following the discontinuation, Riso Kagaku developed the GOCCOPRO series of digital screen makers starting in 2011, offering a modern, computer-to-screen alternative for . Post-discontinuation, Print Gocco retains a dedicated following, with second-hand units and accessories widely available through online auctions like . Users have adapted by employing DIY screen printing kits, such as those using thermofax alternatives or LED exposure methods, and digital emulations that replicate the stencil-creation process via software. Its nostalgic appeal endures in art and zine-making circles, where stockpiled supplies enable limited ongoing use, preserving the system's role as a symbol of accessible, hands-on .
