2. - this does NOT show that they are "incompetent" - one of our PressWise customer took 3,750 orders from Shutterfly on Monday ( yes, all in one day ! ) - and they were probably images taken with iPhones or cheap digital cameras, and if they did have a profile embedded in the image is was probably sRGB ( which is just fine ) and they printed them and shipped them without touching them and customers were happy - how is that "incompetent" ?
As far as I understand (sorry, english is not my native language) you're talking about printing RGB pictures in RGB files... in that case, whatever the embedded profil is, the pictures/files will be converted in CMYK for printing with the CMYK profile of the printer, a profile adapted to the situation (paper, printing process and other parameters that might exist and be involved).
I'm talking about offset printers who want CMYK images (not RGB), claiming that they don't use any profile and don't use colour management, and for that reason they ask their customers to NOT use any profile and/or to REMOVE the embedded profiles in their CMYK picture!
But:
1- it is impossible to convert a picture from RGB to CMYK without a profile... you know that even if you simply click on "CMYK mode" in the Photoshop "Picture" menu, the conversion is done using the (defaut) profile selected in the "Colour preferences" of Photoshop...
But, as far as I have understood by talking with some of these guys, in fact they simply do not understand that a RVB to CMYK conversion needs a profile, they do not understand/know that Photoshop has a selected defaut profile, they do not understand that there is always is a factory selected defaut profile in Photoshop, even if the user hasn't selected one, and they do not understand that this profile is ALWAYS used by Photoshop for the RGB to CMYK conversion, even when simply clicking "CMYK mode".
And, mainly, they believe (wrongly) that to convert an RGB picture to CMYK with a profile, you need to click on the "Convert with profile" item and select a profile... otherwise the conversion is made without profile!!!
2- once the picture is converted in CMYK mode, the profile that has been used during the conversion process has already made the most important part of its actions: it has made the separation, set the TAC and the GCR-UCR, set the max black value and adapted the dot-gain to the paper and the printing process... so the picture is already prepared for the paper and printing process parameters defined in the profile and the remaining job of the embedded profile is only the display correction!
So, removing the profile from a CMYK picture is useless for printing because this action DOES NOT change the adaptations already made in the picture, but only remove the display correction.
But, as the display correction is removed, the operator sees the colour changing on the screen when he removes the profile and then he believes (wrongly) that the picture is modified, althought it is not: only the display is modified.
In the first case, the printer ask the customer to do something impossible, believing that it is possible...
In the second case, the printer ask the customer to make a useless action, believing that it is an important/essential action...
So (in my opinion) in both cases these demands show that the printer is incompetent in colour management.
And the worst is that by asking people to not use a specific profile, they let them use the factory defaut CMYK profile, which, in the french releases of Photoshop since AFAIK Photoshop 2.5 and up to CS4 is a piece of crap inadapted for printing in France!
3. Not sure I agree that "Illustrator is not layout software" - most professional package designers use it,
That's up to you!
But in fact most professional package designers use (or used) it mainly because at the beginning of DTP, when only XPress and Illustrator were available, Illustrator was the more easy to use for packaging... not because Illustrator is better, but mainly because XPress is worst for packaging!!!
Today, professional package designers tend to give up from Illustrator and begin to use InDesign... especially since CS4 and the interesting display pivoting of InDesign 6.
... and submit the files to their flexo house as an .ai file, as the service provider often needs the layers to process the parts as required.
No problem to use layers in InDesign...
In Illustrator, font management, text blocks, image blocks, image handling are pain in the ass...:
- Were are the bleeds and margins in the page settings of Illustrator?
- Try to crop a picture in Illustrator: you'll have to manually mask the unused part of the picture... with InDesign you simply move the limits of the image-block.
- Try to embed a duo-tones picture in an Illustrator document: it will be automatically (badly) converted in CMYK...
(because Illustrator accepts only ONE colorimetric mode... so it is impossible to have a duo-tones picture in a CMYK or RGB document... hopefully for Illustrator users, the RGB workflow is still not yet commonly in use!!!)
- Try to modify the size of a text block using the size's fields in the "Transform" palette: this will modifie the scale of the text (horizontally if you change the width, and vertically if you change the heights)
- And what a stupid idea Adobe had to make Illustrator outputs hybrid .AI and .PDF files by defaut, dramatically raising the weight of these files and confusing users?
AFAIK, only the users of plotters are really stuck with Illustrator, as the plug-ins used to drive their plotters are often developped for Illustrator and CorelDraw, but not for InDesign.
4. As for PSD files - same holds true - there is NOTHING about a PSD file that would degrade the image, ...
You're right! but again I didn't talk about images in PSD... (PSD is great for pictures when imported in an InDesign page-layout!!!)
... but I'm talking about page-layout completely made in Photoshop and sent to the printer as PSD files!
(For example, a 4 pages leaflet is made with 4 PSD files, each page being one .PSD picture!!!)
With 2 possibilities:
- PSD flattened : everything is rasterized... same crap as JPEG or TIFF pages
- PSD non-flattened : in such a file, texts are in vector mode (that's good), but logos are rasterized and 1-bit pictures are in contone mode (that's crap)...
If the printer is a good one, he can keep the text in vector mode... (the rest remains rasterized) it's not that easy, and not that safe, but it can be done... but most printers are not able to do this job and simply flatten the PSD, turnong it into crap
