I have a .pdf that I am trying to send to our printer which has a few color images in the manuscript.  These few high resolution images are appearing to have a weird grid in them that was not present before. What is causing the appearance of this grid and how can I get rid of it?    Also, I pulled down the proof and looked at with Acrobat Pitstop combo and I am realizing that the images are quite massive.  It's telling me that the image is a collection of images (each one in the grid box is a separate image that each have something like 900 x 900 px.  Could this be relevant?

I designed a christmas card and I normally print it on vista print.  When I ask for a print proof the outlines show. They don’t show when I print it at home.  Why are there unwanted white lines appearing in this PDF print proof and how can I solve this problem?

I often see statements in discussions about web displayed image quality that go something like this: "I only upload pictures at 72 dpi and 1200 pixels on the long edge, so if someone copies and prints the image it won't look as good as if it were 300 dpi."  What? Have I missed something here?  Does an image edited and saved/exported with 1200x800 pixels at 300 ppi look any different online than the same image saved/exported with 1200x800 pixels at 72 ppi? Other than the metadata regarding ppi, is there any difference in the two images at all? If so, what is the difference? If I tell my printer to print the images at 4R (4X6 inches) will there be any difference at all in how the printer creates a print from the 1200x800 @ 300 dpi image versus the 1200x800 @ 72 dpi image?

I'd like to know how this text gets adapted onto these 3D models. Could it be a PNG  which gets mapped. Or is this text pre planned how it would be layout onto the model? what's the method involved in this technique? Would the text layout need to be the same ratio done with a graphic editor like Photoshop or Illustrator? and have the mesh modelled in the same metric unit so the text can later fall correctly in place? All information is appreciated, unfortunately my college instructors are really lame in giving information....  Thank you.

I am reading into Illustrator a PDF output from R (grid graphics I believe) in which the circles show as boxes with crosses inside them.  These pictures illustrate:  In OSX Preview:    In Illustrator:    Any idea why this is happening, and how to work around it?  The following Illustrator message pops up when opening the file, which may be significant.

I feel that the PDFs produced by pdflatex are too huge. So for example my 50 page book with no illustrations is 500KB. I feel it should be more like 50K or even less. The .tex files together are just 40KB. Anyone knows why the final PDF is so huge and is there a way to compress it to make smaller?

I'm an Illustrator beginner, and I have just made pie chart. I removed the borders but I still end up with a 1 pixel wide border between the pieces of the pie whenever I export to PDF or AI. Please see the attached image (zoomed to make it easier to spot it).    The question is: How do I get rid of it?

There several types of graphics files. In no particular order .jpeg .eps .pdf .png .tif .jif (and no doubt others). Some work with latex, dvips and some work with pdflatex. How am I supposed to know which?  Just to confuse matters, metapost produces .eps but I can use these with pdflatex as long as I put in a four line incantation.  Can anyone explain this?

Is there a way when exporting a .psd as a .pdf to make the file smaller?   My client always has me work in Photoshop and send them finished work as .pdf's, but they say the files are too big. These products are eventually printed out, so while I need to make the files smaller, they still need to have good quality. Everything is in CMYK mode already. I just don't know a lot about compression and changing file sizes

I make many product photos for the company I work for. For this I use Canon 400D with two external flash devices Walimex CY-600K.  I've noticed an interesting effect on many of the photos I take with white background. On the resulting image there is a red/blue area visible between object and the background. The effect is strongest for black objects and also seems too decrease when I make a brighter photo. It is mostly visible only if zoomed in really close and is not a real problem for me as the resolution is quite high and the resulting images are only 500px wide.   I am just curious as to what is causing it exactly.   For the following example photo I used manual mode with these settings: 1/200 F10 ISO200:  .  You can see blue area left from the object and red area right from it. What is causing this?

In Lyx I'm using float figures.   I have to put three pictures one after the other, so three different float figures.   When I output a pdf, the floats all appear at the top of three different pages.  Why is this happening?

I have a chapter of attachments which contains pdf files in this format, using the awesome pdfpages package:  \chapter{Title} Lots of multipage pdfs following \includepdf[pages=-,frame,scale=0.9]{abc.pdf} \includepdf[pages=-,frame,scale=0.9]{def.pdf} ...   This works, but apparently clears out the header and page numbers of the parent document. What setting do I have to change to get back the header and page numbers?

We publish over 100+ textbooks and growing (1-color, 2-color, 4-color) maninly designed in CorelDraw &amp; Indesign with associated Image and Font Files. We also have merged multipage PDF &amp; EPS files that we send to our offset printers.Also, some Image files are exclusive to a project while some are shared across projects.   What are the best practices to follow when it comes to management of these files? We are always working on multiple versions of the same files and often with multiple DTP operators.  Right now it is all on a Shared Drive with Individual Folders but that always creates confusion in identifying the latest version of the file and some users save the file to some other folder. Security of the Data is another issue as we work with a lot of freelancers also.  How do big design studios and publishing houses handle versioning, collaboration and the associated files with a project neatly? Do they use a CMS / Document Management System?

I changed the background colour of my pdf through:  Document Setup -> changing color under "transparency" (grid color) -> checking "Simulate Colored Paper"  This changes the background in Illustrator as it should. The problem is: if I save the file as a pdf, the background if my pdf is white again :-(  Any idea how to solve this problem? Many thanks in advance!

in the attached image, you can see pixlelation/distortion mainly on the red and blue text and red boxes. What causes this and how can I fix it?  Thanks

I recently had to convert some PDF files to SVG, and did this by opening the PDF in Illustrator, and saving out to SVG.    The issue was that when Illustrator opened the pdf, many (but not all) text objects would be broken up into different text objects.  For instance, the word "policy" wouldn't be one text object, but rather several text objects, "po", "l", "icy".  There didn't seem to be any rhyme or reason to it.    How can I prevent this from happening?

Do you know a good way to compare PDF files side-by-side and show the modifications between the two?  I'm looking for Windows software to accomplish this. It would be great if you can post both free and not-free products.
