CMYK color separation to print in Black on clear film for positive

CMYK color separation to print in Black on clear film for positive

2015-07-06 by sunnyalanoly@...

Is CMYK color separation to print in Black on clear film for making positive for exposing Plate/ Screen is possible with QTR ? Or is it just for converting a full color image file to print better B & W on an Epson machine ?

I am looking a solution for the former: Printing positive on Epson using QTR.

Please enlighten....

Yes it is possible to print CMYK separations in QTR. Of course the separations will have to be generated in Photoshop. Assuming you start with a negative image you will need to Invert the original file to a positive before generating the CMYK files.

Photoshop has limited infrastructure for RIPing, color-separating work. Hence ppl use specialised RIP software to RIP CMYK images.

But to color-sep the CMYK file in to 4 positives of C, M,Y and K, in deep black color tonal range, we need a SOftware.

I thought this Forum must have solutions and QTR an all black system, will have specific steps to color-sep a normal CYMK file to half tone positives.....

I request more insights in this field, how it can be done.

Thank you dongba...

I'm not sure what you are really after but --
A CMYK file in Photoshop is simply 4 channels containing each of the colors.
You can easily make 4 separate files containing one channel each. Then use
QTR driver to print each one separately -- each with whatever inks you want
given the right QTR curves.

Hi Roy,
Thank you for coming for help.

If you couldnt understand my requirement, please take a minute to read the below description on "FilmMaker" RIP of Cadlink Corporation. It is just for informative purpose alone.
Yes, you are correct, it involves separating of CMYK channels in HALFTONE dot pattern, and get those 4 channels printed on clear film using an Epson Sylus printer in maximum Depth of BLACK, to be used to expose screen frames for silk screen printing.

Here, there must be provision for different sizes/ shapes and diff. angles and sharpness of dotes.
I dont know, how far QTR can deliver, but I am sure if you give a try to streamline these features too, so that you can get another set of customer base: CMYK halftone printing clients: they are in 10000s + !!

QTR simply does not have a color engine to do that kind of work. It is a Black and White RIP.

Enough detours exist to make the 4 and up color separations and then print the individual files in black ink only for screening or with more monochrome inks for continuous tones.

If it has to be a fast workflow then buy a color RIP, preferably one with Postscript interpretation, CMYK + RGB support and do the job in one go to an image setter rather than an inkjet printer. Interested in a Wasatch SoftRip license? Includes drivers for a wide variety of inkjet printers too.

Silkscreen printing is commercially a dying profession so I wouldn't recommend any software effort in that direction. Other conventional printing technologies have a hard time too. A 100x140cm 3/4 automat + drying tunnel idle here for near a year. Any interest to purchase it?

Well, I can understand QTR is made for the specific end of monochrome art printing and it is doing it's job pretty well.

But cannot agree that Screen Printing, one of versatile printing method is dying. It is in transition, like many other industrial processes. One has to find other avenues and continue, when current product line is subsiding, that is all.

Anyway it is the developers to decide, if the software can be find another set of buyers, by just tweaking it a little to make it usable for another process, (if it is need not have to make an entirely new one...).

Thanks...

I looked at FilmMaker a little. It's pretty different. Inkjet printers really aren't
for Halftones -- they do stochastic (random) dots to produce levels of gray/color.
Seems FilmMaker simulates halftones but at a loss of resolution and levels.
If that's what you want then I guess the easiest is buying FilmMaker. Most
drivers aren't going to go that route.

Your observation is correct in terms if you want to stick on with Inkjet printing only, yes QTR is made for it and fulfilling its mission as a gift, as a low cost solutio
Halftone printing is for mass-production printing.
My attempt is if I can make use QTR to print black half-toned channels. But think half toning is not in the purview of it, no algorithm for this end with it. Natural, when considering its fiefdom.
