I've got some questions to ask you guys here. Can someome help me out. Had just started using Onyx production house. I also bought the I one pro "UV" ver. I have created some profiles for some third party media. My questions are :
1. After creating a profile for a media, when I send something to print using the just created profile, I notice that yellow is not yellow but luminius green. Has anybody encounter this problem before?
2. I have follow the steps for media profiling very carefully but this still turns out to be the same, have I mised some steps or some button that I suppose to click? ( I have printed the test pic during calibration and it turns out O.K.)
3. In preflight, on the first tab (Printer and Media), under color management drop down list, which do I have to select indor to call for the profile that was just created?
Please help! Any prints that I printed that has had yellow color will turn out greenish.
Please, any pointer will be very much appreciated.
What spectrometer do you use - is it calibrated correctly? It is the most important thing - to have calibrated spectrometer!!!!
How many passes do you use in reading color stripes (patches)?
steps in profiling:
1) linearization - (it's enough for pictures)
2) ink limit
3) icc profile (it's important for spot colors)
then you can do:
4) gray balance...
steps 1 and 3 need to have minimum 3 readings per color patches so that you get as accurate readings as they can be.
So most important thing in profiling is to have calibrated spectrometer. Second thing is to use minimum 3 readings per color patch - more readings will give you more accurate results meaning better profiles...
If spectrometer read that your yellow is "reddish" (when comparing to default yellow - default yellow depends on calibration of spectrometer) profile will put some cyan inside to bring it closer to pure yellow...
It is important thing to have tab "color management" under control. Here you control pictures (files) before you send them to print. So if you select something wrong here, you will change picture before sending it to print - meaning if you made good output profile it want do good prints due fact that you are sending "wrong" picture...
1. in first tab (Profiles) -- you select input profiles put one that you know that are used in creating files (pictures). for example I know that here mostly everybody uses EuroscaleCoated profile for CMYK and AdobeRGB1998 profile for RGB - so I have selected these. For Proof don't select anything.
2. second tab (Rendering Intents) basically this five "intents" are here because gamut of colors produced in printing process (made by inks) is much, much smaller than "light" gamut - gamut that we see. So this five are changing (interpreting) colors that are going outside gamut made by printer. Five different ways. From working experience, perceptual is better for pictures and relative colorimetric is better for vector graphics. So, default setting is good, but it will give you trouble when you will try to print same spot color which is used in same file (.eps) in vector and raster (picture) part - you will have to use one "intent" for both (vector and picture)
3. Output meaning that, output profile - don't change anything here also - this is profile you have created.
sorry for the late reply, I was struggling to get my prints to print the correct colour for the past week that I almost forgot to check back this forum.
Well, I bought the production house Ver 7 together with the Eyeone Pro UV cut. I have follow the on screen instructions to the dot while profiling. I still don't know what I've done wrong to result in yellow coming out lime green when printed.
Read through the manual and there isn't much help. I would like to try using third party profile generator but was told that Ver 7 production house does not accept third party ICC profile. By the way, do you know in which directory does ver 7 store the ICC profiles? Be it canned or newly created.Been going through all the directory but could'nt findany.
Is there any articles on Ver 7 profile creation steps that I can download or walk through the process.
I don't work with v7 so can't tell do you or don't have possibility to import "third party" icc profile. but from this point of view I believe that there is always way to import profiles...
if not, install v 6.5. You have it within v7 installation disks...
-----------------------------------------------
I don't make icc profiles with Postershop. I use Monaco Profiler. In creating profile with third party profile generator you have to be careful when printing it's linearization and icc patches. You have to be careful to print those patches with no profile - so that you get true printouts.
How I do it:
1. create new media in postershop's media manager (in this phase it's empty, with no profiles)
2. using this new media, I'm printing Monaco's linearization file (so there's no profile changing this file)
3. reading (minimum 3 passes per stripe) this linearization patches with Eye1 / Monaco - in this phase Monaco creates icc patches file from linearization readings
4. before printing icc patches, create ink limit - use postershop's ink limit profile builder
5. printing icc patches and reading them in monaco (again there was no profile, except ink limit, messing with files)
6. creating icc profile by reading those patches (minimum 3 reading/passes per stripe again)
7. importing this icc profile in media manager to created media.
so new media is consisted with "only" two profiles: icc (created with Monaco) and ink limit (created by postershop)
this profiling maybe is not the best (accurate), but it's giving me excellent results...
-----------------------------------------------
and just one thing: in first post I told you to be careful in what you select in "color management" tab in preflight.
for example when printing profile patches for profile creation it should be selected "all profiles off"
maybe you have done good profile already, but you have selected (or you didn't select anything, just using default settings) wrong input profiles and they are screwing your files - read printouts...
play with this, if you don't get improvement - you'll learn new thing...
-----------------------------------------------
if you mean on output icc profiles, they are stored in Printer.PrnLib file together with other media profiles and settings.
-----------------------------------------------
I don't have any article about profile creation...
