Question on Quad-RIP

Question on Quad-RIP

2018-01-11 by roscoetuff@...

I have an Epson Surecolor P800, and given the copyright (!!!) mess, I'm pretty much stuck with Epson cartridges. Went with Imageprint by Colorbyte for printing.. which is fine. One day maybe this thing will open up a bit. Love to be able to use the wide range of blacks.


In the meantime, I wanted to ask a question because of course, any change from my current set-up with Colorbyte results in some major $'s.


The impression an outsider gets looking in may not be fair - usually isn't, and I have to say that from where I sit, Quadtone-RIP seems more like Linux software... very capable in the right hands, but requires a level of inner geekdom that not all of us may possess or want to apply here. And maybe it's easier to learn than it looks... but yes, it looks EXTREMELY hard. I did Linux for a few years and ultimately went back to Windows 'cause MS fixed its problems faster than Linux software was able to reach the "finished" point where it was easy to learn. Do you HAVE to take a class to get this? Looks like it. And of course I "know" there's an Epson P800 interface, but what's gained over Imageprint's canned paper profiles, ink matching, etc.


If I ever go out and buy an Epson 3880 or 3800 to get in the game... I guess I'll be in for the whole nine yards. My question is whether or not this software is really getting easier for newby types, or not. Love to hear your thoughts.

I have not verified it by dumping the NVRAM of the printer, but the printer throws zero non-genuine warnings when you use the chip decoder on it. That (most likely) means that if you have a printer under warranty and you develop a problem that is a normal printer problem, you can take the board out, put the epson carts in, do some power cleanings and call for a service repair covered by warranty: they should not be the wiser. I can’t guarantee this until I make sure no non-genuine ink flags have been silently flipped in the count tables of the printer though . . .

As an aside, epson is clearly violating in the Magnuson-Moss Warrenty Act but they just haven’t been called out for it in the courts (unlike HP which was sued and had to back off their firmware update).

Having uses both ColorByte and QTR, I would say QTR is actually easier but just different. You have to learn a few things like installing from an install.command and also the installer itself is not security signed so if you download QTR you have to go to your sec prefs and click “Open Anyway” etc. There are small hiccups that are easily resolved and are really only one-time-things. QTR goes heavy and complex, but it doesn’t require that depth of knowledge just to use.

Are you getting the dreaded P800 banding when using it with QTR?  I gave up and doing my negatives without it.

It is a problem which I have been tackling for many months.

Stay tuned . . .

Best,

Re: Question on Quad-RIP

Is it getting easier? In short, yes it is getting a lot easier than the old way of using a text file with the ink recipe and compiling the quad curves. For the K3 printers I have this: https://www.bwmastery.com/quick-curve-k3/

The QuickCurve-K3 is an Excel based system that uses premade smoothed curves for matte or gloss inks with easy options for adding the toning inks. All you do there is install the starter curves and then print and measure a linearization target for each set of toning curves. The linearization system is built in and has options for adjusting the shape of the final density, so you only need QTR for printing and installing the curves. I just posted the latest update this afternoon that has the addition of the matte starter curves, options for data smoothing (for people on Windows that can't use Data Tool), and a slight change to the linearization formula.

And for the K4+ printers... I've been working on something for the last year and I literally just finished the final piece at 2AM this morning (now I just need a few more screenshots and some edits to the instructions and a webpage and a blog post...). Basically, I wrote my own partitioning formulas (see my QuadToneProfiler-Pro-DN system for how it works for digital negatives). This new version for positives will use the same general workflow along with an additional set of tools for adding and adjusting the toning inks so there is no more need to use an ink descriptor file (I haven't used an ink descriptor file for nearly a year, and I am always making and testing new curves). I hope to have it out in the next week so stay tuned.
