Hi everyone,I have been asked to submit a piece as a PDF and the print shop says that whenever they insert a CorelDraw or Microsoft produced piece they see lines within background images. I'm attaching a screenshot to show what she means. Apparently they appear when they import the PDF into Illustrator. The only way they can and add it to the background in illustrator.Is this something anyone has seen before? I've been using CorelDraw for about 12 years and I don't think I've ever seen it happen or been told that anyone is having it happen to them.Thanks I look forward to hearing other people's thoughts.Phil

so WHY they import a PDF to illustrator? that's a crazy idea, if it's a PDF they should use Acrobat or send directly to the RIP. As an alternativem they can rasterize the PDF with Photoshop, then there's not "extra lines". It's a problem of the convert of PDF to a vector software (it could happens if you open a PDF with CorelDRAW too)
btw under newest CorelDRAW versions you have an option for adjust images to the pixel grid, select the image, right click and choose "object hinting", that should help. The reason of this line is a small difference (half pixel or less) between the image and the pixel grid
They open in Illustrator because that's what Adobe people do.
I would disagree, professional prepress uses Acrobat and or their RIP digital front end, which usually is Acrobat with the RIPs plugin. Any prepress that first opens a PDF in CorelDRAW or Illustrator is causing issues especially where special effects or complex files are concerned.
A CorelDRAW file creator that does not output their files has no need for Illustrator.
Suku said:There is no ironclad rule that says you, or a professional, cannot open a PDF in Illustrator. To the contrary, Illustrator, saves a lot more information with the PDF which serves this very purpose.
I don't have any problem about the people who use Illustrator, but it's not the best solution for edit a PDF file. Moreover, Illustrator is not a PDF editor, some things could change. Maybe you can achieve better results than CorelDARW with some files, but with other files the result could be better with CorelDRAW (although it's not a PDF editor neither). Even if the file ws made qith adobe programs, Illsutrato is not 100% secure for open a PDF. Sometimes it canot read a linked image (but CorelDRAW open it correcty) or can't use the embedded font (but CorelDARW allows to convert to curves correctly) If you talk about "professional users" and PrePress or PrintShops, the only right answer is to edit a PDF using Acrobat and some plugins such as Pitstop. Of course you can open a PDF with CorelDRAW or Illustrator (at your won risk) but it's not the apropriate solution for editing a PDF.
Quoting the original question :

Ariel,
The issue is not about which is a better software. I couldn't care less.
Clearly the client wishes to use Illustrator to further edit the artwork.If you force CorelDRAW down his/her throat, he/she is going to react negatively. I have but suggested how the issue can be solved. The problem does occur when transferring CorelDRAW files to Illustrator. I regularly deliver AI files to print shops who then do further edits based on their customer requirements. I have faced issues similar to what has been stated in the question and have worked around them using a combination of both Corel and Illustrator and successfully deliver AI files without any issues.
The solution in this case would be to deliver an AI file instead of a PDF, and ensure that the stated problem has been eliminated in the final AI file before submitting to the client.
I have only offered an unbiased solution to Phil's problem and nothing more, As a 'CorelDRAW Master' you should too endeavor to suggest solutions instead of digressing into arguments/discussions about which is the better software! Its not about what you, me or Phil or anyone else wants to use. The client wishes to use Illustrator. Either you can deliver to the requirement or not. Simple as that.

First of all, I didn't force anybody to use CorelDRAW. Moreover, I didn't advice never to use CorelDRAW instead as a PDF editor. According my personal experience, each file format should be opened on the right program. And the best program for manage PDF is Acrobat, not CorelDRAW nor Illustrator.
Of course I respect what client wish, but the client could be wrong. Some client want to create a magazine using Photoshop because they know better. Yes, it's possible but ir's not the best option. Maybe the client want to use PowerPoint But this is not the best option, nor the right option. Anyway, if he want to use Illustrator or any other, it's their choice

As far I understand, it was a PDF file created with CorelDRAW, then opened with Illustrator. What I suggested was to fix it with CorelDRAW (using object hinting option) before to Publish as PDF. I suggested to use CorelDRAW since I understand that the file was done with CorelDRAW. Simple as that.
[Y] I am out of this thread.
