This article covers technical and architectural choices in modern web-based design tooling for applications requiring high fidelity, including print.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Geo\/GIS applications, light-sensing applications, medical imaging, and print applications handle data that cannot be accurately represented by static, 2D RGB screens.<\/p>\n\n\n\n

Within print, we have CMYK coloring that can fall outside of the sRGB gamut, spot colors, pantones, and specialty ink, including neon and UV reactive, foil masks, embossed and other surface-deforming alterations, and specular modifications including UV spot and other effects, like matte, semi-gloss and gloss finishes. These can be approximated for non-professional users.<\/p>\n\n\n\n

Shown above is the accompanying demo application, which shows an exaggerated gold foil effect written in OpenGL’s graphic shader language being composited over a Fabric.JS instance with a custom interface.<\/p>\n\n\n\n

Demo Coverage<\/h2>\n\n\n\n

Supplied with the demo are three novel libraries created to demonstrate the principles behind composite applications with end-user friendly wizards.<\/p>\n\n\n\n

* Builder<\/strong>, an assembly for converting masked shapes and managing graphcs shaders),
\n* precision slider<\/strong> – a micro-ui element,
\n* Tiff-Writer<\/strong>, which exports high-fidelity TIFF files with embedded, editable multi-channel spot color channels.<\/p>\n\n\n\n

Not included: Spot Registry, allowing mapping to 5+ color digital presses with formatted asset bundles with uncompressed 300 DPI resolution and embedded ICC profiles for reproduction.<\/p>\n\n\n\n
