Printing Negatives on OHP Transparents Alternative Processes

[emankayker]

Hi
I'd like to start printing large negatives for alternative processes and don't know how to get the density and right curve for a good final print.
How could I produce an ICC with my color munki?
Anybody with experience with that matter?

is it about halftone printing ? or simple B/W - 2 color ? Which format - which printer ? What is going to happen with the films ?
There are alternative B/W inks for refill on the market offered from some ink suppliers. But for a good print the film material must be selected carefully - the surface makes the difference how good the ink stays on the film.

This is a rather specialised application and I think you may get better rersults on other forums. For example, the making of digital negatives is often discussed in the QTR Yahoo group. Try searching on https://groups.yahoo.com/neo/groups/QuadtoneRIP/conversations/messages QTR seems to be the tool of choice for this application and you should find various links to other resources.

thanks Roger, that looks excellent!

@Ink stained Fingers
The purpose is to have the most density onto transparency, and the right curve from one tone to another as each way of reproduction changes...
The negative is then pressed onto a sensitived paper and produce the final print,
I'm using a 3880 so I am looking for the deepest black possible on a trasparancy. So any input is welcome as what ink supplyer to use for that.

An alternative to trying to get different types of ink why don’t you explore the use of the many different media settings that your printer has to offer.

While using your film set your printer to use one media setting then another etc, that way you might get a satisfactory setting that works for you, use setting that only uses one black first and then use the other black..

Hi Hat
... well that's a musician joke I suppose
that sounds like a good idea, but I didn't know some settings would use only one cartridge. Do you have an idea which one only use the 3880 PK?
thanks

there is a special Piezographic ink set on the market specifically for B/W printing, and that is claimed to have a better black level than regular inks. So much for the dark part, but you want to print halftones as well. You need to consider how you want the achieve the transparent halftone effect, you can do that just with dithering, or using transparent ink - dye inks. Since that your target paper is most likely monochrome it wouldn't matter if your negative is printed with dye colored inks. Please be aware that pigment inks, the pigments are not transparent, they only create reflective colors, and overhead transparencies with pigment ink look pretty dull. I think the most difficult part would be the creation of a 'color' profile, actually only a gamma like profile to adjust the film print to match the target exposure performance.

Use Quad Tone Rip it will work the way you want. You can also make ICC profiles for that that will solve the plugged shadows so to speak if you don't want to hand tweak the RIP. Some films inks require ICC to work properly.

Printer driver just controls your printer as RGB device, you want the CMYK control individual channels that is why you need RIP.

By using the different Media settings you can use both PK and Mk blacks and just use the greyscale if you prefer and it may put down enough ink with just the one cartridge.

A blacker image can be had by printing two images and registering both of them together to form one uniform image, I have used these setting myself.. (2 Separate sheets)
