Tasks

There are compulsory questions for this semester I didn't answer before, so I'm going to answer to them now.

What's the importance of using bleed & margins when sending packaging/publishing jobs to print?

Bleed and margins are the most important things to make a printed document look professional and well-done. Basically, Bleed is the safe zone outside the trim area of the sheet. If the document has images that touch the edge, they should extend at least 3mm outside the sheet, so that no white area is visible after print. Margins are the safe zone inside the sheet. They have pretty much the same purpose: to make the printed paper look professional and good. Margins are usually put for the text. There should be at least 8mm margin between text and straight lines.

What's the difference between RGB and CMYK?

These are the two formats available to print colours. RGB stands for Red, Green and Blue. Is the format used for on screen pictures. Since the monitor emits light, pictures in this format would result bright and beautiful. But if an RGB picture is printed, the colours would result less bright and vivid. That's because paper, unlike monitors, can't emit light, it just subtracts colours. This is where CMYK format shows up! CMYK stands for Cyan, Magenta, Yellow and Black. This is the format used for print, as the combination of these colours allow to print digital images without colour alteration.

What does "dpi" mean?

"Dpi" is acronym for dots per inch and it refers to the output resolution of a printer. An image with an higher dpi will be printed in an higher quality than one with lower dpi. On the other hand, files in high dpi have big sizes and take more space. If you want to create a document to be seen just on screen, lower dpi files are fine.
300dpi = higher resolution
72dpi = lower resolution
