Tiff can support 8bits per channel CMYK. JPEG can support 4bits per channel, CMYK. That means CMYK has 256 levels of fidelity, per channel, per pixel. JPEG only has 64, and makes up for it with dithering (patterns). As a result, there's much less information in a JPEG, and much less data to work with when making adjustments.
So, tiff is better for working files as it is higher quality, which can always be reduced, but not increased, and it doesn't lose information over generations like JPEG does. Also supports clipping masks, different bit depths (ie: 1bit) layers and is just generally superior to JPEG in every way except file size, compression speed and rendering to screen (less bits to process).
- CMYK does not work with 256 levels, it works with 0-100% per channel.mekk
- That's what Illustrator shows you. Raster pixels are saved as N bits/channel. 8^2 is 256. Therefore you have 256 possible grey levels per channelmonNom
- Ugh, brainfart, 2^8 is 256. Anyways, the 256 colours is why you can use decimal percentages for ink levels. (ie: 55.5%)monNom
- 2^4 = 16, btwnb
- oh man, keep me away from the math.monNom
