Effect › Color Effects › Duotone… (addon.color.duotone, also in Object ›
Plug-ins › Color Effects) prints the grey-equivalent tone of each colour
with one to four inks, each with its own tone curve. It is a colour
adjustment like the add-on's others, so it stacks with them and works as
a filter through addon.color.filter.
- One tone of a swatch the document has gives a tint of that swatch,
linked, so a spot tone separates onto its plate; several tones give
the CMYK mix of their tints (the inks overprint, so they multiply).
- Colour adjustments now map paints with their swatch links
(ColorMap::apply_link); the existing adjustments behave as before.
- Skip Objects with Spot Colors leaves spot-linked colours as they are.
- The dialog has a row per tone and the picked tone's curve (the Curves
graph, reused), its points and Reset to Linear / Inverse.
Print Ink Fixes (addon.color.printFixes, Object › Plug-ins › Color
Effects › Print Ink Fixes…) scales CMYK colours over a total ink limit
down to it, removes white overprint and sets black overprint (Overprint
Black's logic) in a CMYK document, as one undo step, and reports what
changed. RGB documents are refused.
The panel opens both under Inks.
Deferred: an opaque undercoat, tones for type only, extra gradient stops
for smoother tints, curve flip and all-100 % buttons.
Effect › Color Effects › Vector Halftone… (addon.color.halftone, also in
Object › Plug-ins › Color Effects) draws its object as the halftone dots
Object › Vector Halftone makes, live: mono (one dot colour, or each dot in
the art's colour under it) or CMYK screens, the five dot shapes,
frequency, angle, invert and clip to the art's outline.
- The screens, dots and caps move to vectorcraft_effects::addons::halftone,
shared by the command (its behaviour and tests unchanged) and the effect.
- The renderer samples the art (vectorcraft_render::addons::halftone) and
keeps the dots by the object's content and what it reads from the
document, so unchanged art isn't sampled again; past 100000 cells per
screen the object draws as it is.
- Expand Appearance turns the object into its dots, and the SVG, PDF, EPS
and AI exporters write them as paths.
- Its dialog reuses the command's fields, without Keep Original.
Deferred: stochastic and radial patterns, a dot-gain curve, per-screen
separation settings, type or symbols as dots.
A built-in add-on in Effect › Color Effects and Object › Plug-ins › Color Effects:
- Exposure (stops of linear light, offset and gamma), Desaturate and
Invert Colors as live colour adjustments, evaluated in stack order with
those of Effect › Color Adjustments.
- addon.color.filter applies any colour adjustment to the colours
themselves, through the Edit Colors pass, as one undo step.
- A panel picks an adjustment and its values, then adds it as a live
effect or applies it as a filter.
The add-on lives in its own modules (effects, engine and ui-egui addons
folders) and leaves the existing effects, commands and menus as they
were.
