Can QTR do the following

Can QTR do the following

2005-03-25 by Ranjan

Hi,
I am a new user of this rip, at 1st glance its quite feature packed I 
want to do the following but cannot figure it out how to do it.

1. I dont have epson 4000/10000 but a commercial printer in our city 
has these printers & I want to rip the file so it can be printed 
there. Is it possible to "rip to file" or else I have a cute Pdf 
printer which can print  & convert all files to pdf, but QTR does not 
work with it, it shows spooling but saves a blank pdf file.

2. I want to make a test strip of all combination using various 
profiles, can QTR make small images 2x3 inch on a a3 size so I can 
compare which one to choose from.

What does different Dithering alogrithm do, is there any description 
of each as to which image I should use what alogrithm.

Not really. Say you're ripping an Epson 4000 image, 16x24 inch. At 1440dpi, that's 16*1440*24*1440 = 796,262,400 pixels. Each of these needs a value for 7 different inks (even if some aren't used, they still go to the printer as "off") and each ink has five states. So each pixel "fits" in 3 bytes...

That means you're at 2.38 gigs per image. If you burnt that to DVD, it might work. Maybe. But I've never heard of anyone trying.

And if you try to pull a 44x66 off that Epson 10000, you need 18 gigabytes. You can't get it from here to there...

The three best possabilities:

1) show him some QTR prints from a smaller machine (do yu have an Epson 2200) and teach him the joys of QTR. He might want to start offering QTR prints.

2) Find out if you can go in with a laptop and plug into his printers.

3) Find out if he's using another RIP, like Onyx or ImagePrint. If so, find out how good he is at making monochrome images on that RIP.

That's because there's no way, in PDF, to represent raw data going to a printer.

Yes, I do that all the time. But the printer has to be local to you. You have to keep changing the image placement manually through QTRgui.

That's been described several times on this site. You'll have to search.
