Onyx Pre-flight not showing image

I thought I would check to see if anyone else has had this issue and come up with a solution before I call Onyx and spend the $$. I've got a series of 5 prints that are about 112" x 356" with file sizes around 2.5GB, saved as .TIF. These are client supplied files. When I try and open one of the files in pre-flight it takes a few minutes to open, then only shows a black square as the image but not the image itself. I have tried changing media etc. but nothing works to bring the image which wont let me output, gives me errors on the rip. I'm starting to get in a bind on this as these prints have to be installed next week.

a few things to check...

has this happened before?

is your RIP station equipped with enough RAM to handle such large files (do you normally work with files that large)?

can you open the customer supplied file(s) in Photoshop, and it looks correct there?

do other files open and preview correctly since this series of files has given you problems?

if RIP is ok with other files, can you resave the original files without modification and then test if they RIP correctly (like a file you would have created in-house).

can you save a copy that is a reprocessed slightly lower res version of the original customer supplied file. ie: if it's at 100ppi at actual, does the file lend itself to resizing to 75 ppi at actual size? does that RIP properly?


these are the first steps i would test to troubleshoot any stubborn files.

it seems to me to be a RAM issue or a corrupt file based off the info you have shared.

Two possibilities:

1. The files have been saved using a form of internal file compression that Onyx cannot decipher.
I have tested with Onyx 11 various types of internal TIF compression, including LZW and JPG, and have not encountered one that Onyx cannot work with. Earlier versions of Onyx may not support all variants (you didn't mention the version of Onyx that you are running but I assume it to be 10.1 or lower). If compression is the case, you should be able to open the files into Photoshop, and re-save them using no TIF file compression, and this should resolve the issue.

2. The files may be too large for Onyx to process. I do not know what the maximum number of pixel rows/ columns that Onyx is capable of rendering, but this could be exceeding the maximum. If that is the case, again you should be able to take the file into Photoshop, and lower the file resolution to generate a significantly smaller file that Onyx would be able to process. Something that size I would say that 120 PPI (or somewhat less) should be more than sufficient.

the PC has 12GB ram installed

Running Onyx 10.2.5.45 - never had an issue with TIF files before

I am trying to re-save as TIF again with no compression and see if this works.

i have good results saving compressed *.TIFs w LZW image compression, interleaved, PC byte order, RLE layer compression.

saving as a flattened *.TIF for print output may reduce file size too.

another option would be to save as *.EPS from Photoshop with 8-bit/pixel tiff preview and jpeg max quality, much smaller files sizes and fast RIP handling.

I'm trying to save now with LZW compression, interleaved, PC Byte order - wont let me use layered compression (greyed out). The artwork has been flattened before I got it.

Also for some reason it won't let me save in any other format other than .PSB, .RAW, .TIF.

there is a maximum file size that it will allow you to save as, go over that limit and you're stuck with the 3 'save as' options you have. if your current save doesn't work, try dropping the resolution, then re-saving like you would your normal workflow, and see if that outputs correctly.

edit: forgot to ask, what is the original file type, size, and resolution? example: 203mb layered *.psd , CMYK at x x y @ z ppi

I'm not sure what the original file type etc. was, I was just sent a set of 2.5GB Tif files that had all been flattened.

It looks like the re-save with the LZW compression has worked. I was able to view the image in PF and it is now ripping, which is further than I had gotten before so hopefully it works but I don't see why not now unless there is an issue with the RIP.

Thanks so much! you just saved me time money and a headache!
