Yesterday I worked on a new digital file for a client, looked great. Printed out an A4 version to see what it looked like, great! Printed out a huge great A1 print and hey presto, something doesn't look right at the large scale so I rework the file. Print another A1 print and THIS TIME there is banding where there was none before! I haven't used the large 44" wide printer for a while so I guessed it needed a bit of throughput. Ran print head checks, then printed a 24" wide test strip, still the same problems. Ran a print head alignment test and another 24" wide test strip and STILL banding. Ran a paper advance calibration on some A2 paper and then did ANOTHER test strip. Success!
So now I reload the roll paper and send another A1 print through the machine and as I'd hoped, NO banding, but when I looked at the sky area of the print there was a prominent dirty blemish WITHIN the paper itself - aaarrrggghhhh. I am now printing my FOURTH attempt at this image which blemish depending will look great - this is just to let you know that even when you spend £6K on a profiling printer, it doesn't mean it's trouble free!!
Just checked it, it's looking great and the client will be happy, but it's taken most of the afternoon and shed loads of money to get this first print out, the things people don't realise!
