Hi excentrique, thanks for bothering to explain all this. My issue is actually when it comes to printing. I've used adobe gamma to do the calibration of my monitor, but when it comes to printing, I can't get my prints from the photolabs to come out the same as what was on my screen. Any advice on this would be appreciated
Okay if you have read my lesson 2 on monitor calibration, you would understand that if the other party who does not use an ICC profile or are not using the same ICC profile as you do, the other person might not be able to get the same result as you.
From my experience, even by using the attached ICC profile by photoshop, there would still be colour shift when it comes to printing. Infact, adobe gamma is still far from proffessional reliability in production line. There are however top of the line and much more complex calibration software in the market which are extremely costly and this is just the starting of even bigger issues.
Well, why you are not getting the print even though you have done a ICC profiler? Apart from the accuracy of the ICC profiler, different types of printers (domestical and commercial) have also different characteristics and they interpret colours differently. For example, epson photo print will look different from espon stylus, and within different brands itself, there is a difference it terms of technology and use of pigments and inks. In commercial printing, different printers, chemicals, papers will all interpret colour differently.
Inorder to do a good print, you would realise by now that one has to understand his or her printer and brands of ink as well. If your monitor is profiled, (balanced) and you found that your home based printer has a slightly yellow cast (due to the nature of your printer capability), you would have to correct it in the software to get a balance picture.
You could create another profile in photoshop to tell your computer to print lesser in yellow pigment for example in this case (make sure you use the same brand of ink). With the recorded profile, you could activate the printer profiler so all your prints would come out balanced.
However, this is only solely for your home printer. The commercial printer would have another standard of ICC profiler for their printer and monitor, that is entirely different from your's. That is the reason why it is almost impossible to get close to what you want.
There are several ways which we can now solve the problem:
1) Use the same ICC profile (monitor and printer) as your commercial printer. As far as concern, most printer would have their set of ICC profile for thier printers. If they are using photoshop like you do, you could request them to send you their ICC profile (for printers only) and attached it in your lists of preset profiles. This would ensure that when they open up the file in their computer, the colour shift has been corrected. However, I don't think this is a common practice in local market. Commercial printers normally do not give away their profiles to their clients. Apart from this, you would also not get the right colours if you are using another commercial printer the next time round as their ICC profile would be different from earlier one you took the profile from.
2) The more feasible option is to use a hardcopy proof. If you could do a good calibration of your monitor and printer, it would be good to do a hardcopy print first on your home based printer for your commercial printer to gauge. Yet, this is a very laborious process and time consuming.
There is no better way to solve this issue yet as far as I know unless you use the same profile and common software with your commercial printers. That is probably why hardcopy is still around as a more reliable form of gauging.
