NotMyFault Posted December 19, 2021 Share Posted December 19, 2021 Hi, it is not possible to access the K channel in CMYK color mode. When you try to use K as variable within the formula, the filter stops working. All other channels work as expected (C, M, Y, A) The test file has 4 formulas. Only one of these should be activated at a time (on alpha channel). If you activate the formula containing K, it does not work. I tried all capital letters, only CMYA work. K active: does not work CMY active: works limit workaround: use a channel mixer to remap K to any other channel except A. Unfortunately does not help when you need access to all 4 channels. A channel not usable as workaround, as A=0 overwrites all other channels with 0. PT CMYK K not working.afphoto Quote Mac mini M1 A2348 | Windows 10 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.
