I have recently made a book for my college project which I have had help with before on here, some problems the print maker has been having with my work is that:
1. On this poster the drop shadow didn't print from the pdf, it's like it was none existant.
2. On the pages of this book where I have imported .png files (high res) from Photoshop, the printer has been printing the transparent parts darker. (I've edited the image to show what happens after printing, the darker area being the transparent area of the .png)
I have read about flattening transparency but I'm a bit confused as to how it works.
Could someone help me please?
I'm not sure why the drop shadow would be missing, but it could be a printer issue. The dark color on the transparency is most likely Yucky Discolored Box Syndrome ( see InDesignSecrets » Blog Archive » Eliminating YDB (Yucky Discolored Box) Syndrome) or you've selected CMYK as the flattener blend space and you're working with an RGB image.
Is this for final output, or just a proofing step? I thought it was going to go to a commercial printer, and they should be providing a "contract proof" before running the job.
I think it might be a printer issue for the shadow as well.
This is for final output, but I know the people who work at the print company so it's fine, the pictures look fine on the PDF but after it has been printed the darkness occurs, so is it the flattener blend space that needs changing?
Thanks for the fast reply Peter.
Sorry I should explain better, the output is from the commercial printer, I am using the "High Quality Print" with the settings we discussed in the other thread where I had issues with the crop/bleed and page numbering.
Right. I recognized the job.
The High Quality Print preset leaves transparency live and colors unchanged, so this is happening at their end. Is the print run going to be digital or offset? Did they tell you to use that preset?
Digital printing I believe, they didn't tell me a preset I just assumed that high quality print would work fine, I don't think they've encountered this before so I thought my document settings were wrong.
First thing would be to ask them for a preset they want you to use.
Next would be to convert the .png files to .psd and see if they work better. I've never gone to print with .png, and while I think it ought to work, it's really a web format.
A small issue i'm facing is, i've set my Creative Suite Colour Profile to synchronize to European General 3, but when I export from InDesign it says :
1) The preset specifies source profiles that don't match the current colour settings file. Profiles specified by the colour settings file will be used."
Should I just "Convert to Destination" in the output tab?
That warning pops up all the time. The good news is it's telling you that the conversion will use the profiles you specified, not the ones built into the preset. Presumably you've got the working space set to European General Purpose 3, and the destination is the same? That should work fine for color.
I'm worried about a flattening artifact called "stitching" though if you flatten the file on export. It shows up as a thin white line around the transaprent regions onscreen in the PDF and may be visible in a digital print, too. What settings are you using now?
Colour Conversion: Convert to Destination
Destination: Coated FOGRA39 (ISO 12647-2:2004)
Profile Inclusion Policy: Include Destination Profile
Simulate Overprint: N/A
Output Intent Profile Name: N/A
Output Condition: N/A
Output Condition Identifier: N/A
Registry Name: N/A
That's what I have for output, I did some messing about and I think I saw what you were talking about. It hasn't done it with this export though.
Just to let you know as well as changing the png to psd's I also ran the exported pdf through the acrobat x pro preflight check for digital printing (color).
Yes I set it to Acrobat 5, I looked on the Adobe support and tested out the Acrobat 4 where it does flatten it and saw the stitching if I remember, I also tried printing the indesign file to a pdf and seeing what happened, the transparency showed a little change like so:
Ive sent the PDF off now so we'll see how it turns out, if it doesn't print properly i'll have to explain that in my project evaluation and be done with it, fingers crossed though and again, thanks for the amazing support!
Printing to PDF always flattens the transparency becuse it uses a postscript file and distiller, and postscript doesn't support most advances PDF features, including layers, interactivity, and transparency.
