Avoid PS CS5
Been using this for a few days now and just did some wrap artwork.
Saved the images as Jpegs but when I open them in Flexi or Shiraz RIP they are being resampled to 72 DPI and thus end up being much larger than the original document size they were set up as.
Having checked on Google it seems that loads of people are having the same issue with Corel and multiple RIPS.
Turns out Adobe (being Adobe) have changed they way Jpegs are saved to a more ‘technically correct’ way, which is of course a PITA to eveyone else!

Hi,
why are you using the files as .jpg? Is the worst format for files. Everytime when you will open and close a .jpg file you will lose pixels informations. You can try this with a file. Make a copy of the jpg and open one of them for 50 times and see the differences between them after that. Use the .tiff format or .psb for large file format. These types of formats will keep the infos. -
Catad, surely the final output file is OK as a jpg once all editing is done in the native format?
-
If you are saving the file as .jpg only when the job is done and ready for output will be ok. Just remember that a .jpg file will not accept transparencies as a .tiff file will. If a JPEG image is opened, edited, and saved again it results in image degradation. If you must perform editing functions in several sessions or in several different programs, you should use an image format that is not lossy (TIFF, PSB, PNG) for the intermediate editing sessions before saving the final version.

I tend to agree with Catad. I do not use jpeg at all if I can avoid it. Tiff is my preference if I can’t use eps or pdf files to rip or bring into my sign software..
I have CS4 and find it useful when my clients send files that will not import into corel, although X5 has got their act together in terms of compatibility, but CS4 does cause me grief from time to time, especially if distiller has a hiccup, then life becomes a bit of a drama..
I just bought CS5 today, but not even unpacked the software yet. I need it for the clients that have upgraded and insist on sending me psd files because they don’t want to acknowledge any other software at all. 🙁

I agree with what’s been said already. Shiraz requires the input in 1 of 5 filetypes. EPS, PS, JPG, PDF & TIFF (although AI and PLT’s work to a slightly lesser extent). My general preference is to use EPS from Photoshop and Illustrator for the best results. JPEG is great for portability but not as good for hi-res output.

Try to make a small text file with files specifications and send to your customers. I will not accept a .psd file from a customer for print if the customer is not there or he’s not give me an approval for colors first. The psd files can be a lot tricky. The best is pdf or eps file for vectors or tiff or psb(for very large file up to 300k pixels in each direction) for raster files. Taking the psd you can have the surprise with fonts, hidden layers, a lot of troubles. flattened image, tiff format, cmyk or lab.

graphic artists are a law unto themselves here catad. They are the hardest people to deal with at the best of times. 👿

Oh noes, I am currently reviewing Adobe products as we speak.
Our old JV3 is running with Shiraz 6.4, an old version now. We feed it JPG as it sometimes fails with newer PDF formats, however Shiraz struggles with CS3/CS4 Photoshop PDFs and we save back to JPG, you do sometimes get sizing issues and you must keep an eye out for it.
Good to see you Stafford, are you still with Ramin? (Shiraz)

Hi Dave, I hope you’re well? The London and Kent offices are running quite separately these days but we are still right in there with the whole Shiraz thing.
Unfortunately, you will get the odd ‘quirk’ in Shiraz v6.4 when being faced with more modern file content. After all v6.4 is at best a 2 year old RIP now!! The first release was Jan 2007 and the final was Jan 2008. How time flies, eh!!?? 😀

Ah!
So this will be why I’ve started having problems with SOME Adobe generated PDFs as a customer has switched to CS5. Normally end up with missing content in the print / black sections although the on-screen view was fine.

I’m on CS4 and have been thinking about upgrading as I saw a lot of good new features in CS5, I’m concerned now about it and wonder if it’s worth waiting a while and hopefully these problems will be fixed.
or is it still worth while to go for it now?
cheers

I use pdf and eps mainly but I find jpg good for when a customer emails a file for printing, then it’s fine and there is very few compatibility problems

I used photoshop to sort out those bad files that an old rip cant handle

Photoshop seems to have been the best way around things for some time now Dave. I would never advise people not to upgrade their Photoshop just because of their RIP, I’m sure there are far more plus points to the upgrade than there are negatives. And there are always ways around these problems, paricularly with the amount of knowledge floating around on the forums.
