Anybody using AI up for a challenge?
I would love to see the results.
So, take any random, say, picture download one of mine that I have posted, or use one of your own.
I want it seperated into cyan, magenta, yellow and black. I want a halftone screen with a round dot at 150 lines per inch and the seperated results in one bit tiff.
And if you want to get freaky ask the AI to apply a tonal value increase corresponding to a KBA printing press.
If it works as I hope then the multi million raster image processing industry of Kodak, agfa Fuji ect is basically fu ked.
How does this look?

input_K.tif (523.8 KB)
input_M.tif (717.5 KB)
input_C.tif (788.8 KB)
Wont let me download.
Perhaps via email attachment?
Oh, almost forgot:
Cyan needs to be angled at 15°
Magenta at 75°
Yellow at 90°
And black at 45°
What the hell is AI file sharing?
OK. I just uploaded original image and TIFFs instead.
But I’m confused, isn’t conversion to CMYK just a standard feature on various graphics programs?
It is, normally, photoshop can do it, but not very good, the halftone screening is limited and more of an applied filter.
Thing is people are tring to leave Adobe due to their subscription policy which basically holds your files hostage subject to a monthly fee and is so expensive that people who are not in the industry will have no use for PS.
I use Affinity which is (for now ) free unless you use the AI option.
It can also seperate in roughly the same way as PS, but as I said, its rather clumbersome compaired to a dedicated and even more expensive RIP and I was just wondering if AI could do a more streamlined job.
It would mean that a private person or a small company could simply upload their files and get a solution to rival dedicated hard and software.
Let me know if the quality of the above RIP is OK.
It uses AM screening and rotates with standard Webster angles.
Looks interesting, I’m underway today, but I’ll proof it this evening.
AI supported speech-to-text online service. Wife got a voice message where I understood most of it, but missed the key idea (this weekend, not next weekend) in my interpretation. So, AI helps:
I’ll go back to German courses in August.
WOW! the resultes are pretty viable for a first attempt, mind you there are no curves implemented and no colour corrections and no compensation for TVI.
The image comes over as 1200 ppi which surprises me as I would have expected a much lower resolution and a CCTV4 compression which is typical for a tiff.
The round dot has a clear centered rosette and this I would say is a sellable result. (after color managment implemented)
I specified output of 1200 ppi (but output resolution can be whatever you want.) and applied FOGRA39 profile which should have some implicit TVI. The TIFF files do actually have CCITT Group 4 (lossless) compression applied. It would be possible to add a feature to apply 1D press-calibration LUTs prior to halftoning to allow for specific on-press TVI compensation.
I only have the “lite” version of firstproof, so I cant evaluate the dot form, but that is a really good result.
There’s a color shift versus the original, when you did the proofing, did you use a specific profile e.g. use same FOGRA39 that I used for the conversion?
I’m still looking-tbc.
No, firstproof takes the RIPped tiff to make a virtual proof of what the printed product will look like, any correction is done in the ripping stage or in the pre rip .
Now I’ll fire up affinity and look at the composit.
