[Photo and Designer] Spot Ink multichannel format

Recommended Posts

I know this is a feature hard to implement, but i have to ask for it.


I compose some magazines with 2 Spot inks, usually Black & any Pantone ink. I don't like to use that method, but some customers seems to like it and it's cheapper to print (in offset press) than full CMYK. So, i have tu use that feature. It's the only feature i miss, both in Photo and Designer; so, i have to use Adobe Photoshop. So, this is the workflow in Adobe CC suite, and i it will be nice to have it in Affinity apps...






- First, create a 8bit gray image

- Change format to Multichannel (you are not allowed if you don't change first to Gray)

- Add many channels as you need

- Change Spot color of each channel


This is not just Duotone/Tritone, etc... Is full channel working. You are allowed to paint any part of the channel, not just all the channel as a whole image. In those examples, i just coppied Cian or Magenta channels of the orinial image, then coppied directly to Spot Channel.


Image must be saved in .eps DCS 2.0 format. It's the same format as duotones, but you are allowed to edit channels directly (duotones are curve variations of the same 8bit gray channel).



Compositing (Indesign):




- Import your DCS 2.0 image. The spot inks of the image are auto. incorporated to document swatches. 

- Then, yo can create mixed inks, with % of each spot ink yo wish. You can also add gradients based on those mixed inks.
