Wil JF Posted October 24, 2023 Posted October 24, 2023 I'm producing some illustrations for printing in CMYK and tried changing the blend mode of all the black strokes to multiply in the appearance panel to simulate overprint (since the configuration mode through the global swatch doesn't work when exporting to tiff). I made the selection in the "select same > stroke color" item and with all the strokes selected I tried to change it to multiply in the appearance panel, as said. However, no changes are made, keeping the Normal blend mode as the default setting. Is it possible to check this or only single selected strokes can be changed this way?

NotMyFault Posted October 24, 2023 Posted October 24, 2023 I‘m surprised to see blend modes used in combination with CMYK documents. This might work in some simplistic cases, but in general is calling for trouble. Blend modes (except normal) are based on additive color models, and in most cases will not produce expected or reasonable results in subtractive CMYK.
