The final goal of sending any files to Mel Printing should be to have a press ready PDF. What does that mean? It means...
- Images in the PDF needs to be high resolution or preferably vector.
- The file needs to have a bleed on it.
- Fonts should be embedded properly in the pdf.
- Colors should be converted to CMYK when possible
To clear up some confusion bleeds are a 0.125 inch extra edge around the PDF that makes the colors run off the edge of the paper. The reason this is necessary is when we go to cut the piece if the piece is exactly to size you may see a tiny sliver of white on the edge. So when you are creating an 8.5 x 11 piece the final size of the PDF needs to be 8.75 x 11.25. Sometimes programs like inDesign will leave you with a final file size of 8.812 x 11.314 and this is fine as long as the bleeds are there and can be identified by crop marks.
As for fonts, colors and image resolution normally these will work out through the process, but it's always good to make sure that the above points are looked out for as to not have any issues down the line.
