Screen Print Guide screen printed reference book by Jan Konsin

The dots in the angles, the moire in the threads! Screen Print Guide with special reference to halftone rasters and transparencies by printmaker Jan Konsin of Kalasataman Seripaja is our most ambitious book to date (15+ screens on 4 sheets!), printed together with the author during a feverish week in April 2026. and co-published with Finnish Rab-Rab Press. The systematic, tactile review of halftone shapes, resolutions and angles makes this pile of paper an indispensable treasure to the screenprinter’s internationale. Page after page of technical detail but not a showcase of flawless lines, rather purposely hitting the limits of our equipment’s precision and touching the borderlands of screen print capacity (as far as line weight go). If you need it you know you really need it.

A raster dot is a tool used to simulate gradients and tonal variation. Large dots appear dark, small dots appear light, and no dots appear white. In screen printing, it is impossible to print a smooth gradient—only solid ink or no ink. The raster dot solves this problem. This guide illustrates raster sizes and shapes, as well as how changes in dot size, spacing, form, and angle impact the final print. It also explains the moiré pattern—those wavy lines that appear when dots interact with the screen mesh—and how to avoid them. In addition, it showcases handmade originals—drawings created directly on transparent film using various media. One spread illustrates transparency and opacity when printing overlapping solid colors.

The images in the book are arbitrary; they demonstrate the workings of halftone rasters and transparencies, as well as their failures. At the same time, they testify to the world of Kalasataman Seripaja and Longest Night—autonomous, collective screen-printing workshops in Helsinki and Gothenburg. These images reflect the social, emotional, and environmental surroundings of the workshops.

Additionally, the guide features a complete translation of Vujica Rešin Tucić’s Reform Grotesk, condensed into two pages. Originally published in Yugoslavia in 1983, these sound poems address the materiality of print, including rasters, fonts, type, and their politics.

Conceived by Jan Konsin and edited in collaboration with Mark Kuivanen, the guide was produced entirely at the Kalasataman Seripaja workshop in Helsinki and the Longest Night workshop in Gothenburg, between April 22nd and 30th 2026, in an edition of 150.
