Screen Print Guide with Special Reference to Halftone Rasters and Transparencies, by printmaker Jan Konsin, published together with Longest Night, is the systematic and tactile review of halftone shapes, resolutions, and angles — an indispensable resource for screen printers’ internationale.

In screen printing, it is impossible to print a smooth gradient—only solid ink or no ink. The raster dot solves this problem. Screen Print 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.

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.

Page after page of technical detail, but not a showcase of flawless lines. Rather, it purposely pushes the limits of screen printing equipment’s precision, touching the borderlands of its capacity (as far as line weight goes).

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 10 April and 1 May 2026, in an edition of 150.
