I had no idea about how to use InDesign to complete my design work two years ago. What I knew at that time was the functions of each tools on the left sidebar. But, I knew nothing about about secret shortcut keys no mention to tips and tricks. And I know, most of you must be the same as me that we do not want to spend thirty minutes even longer to watch a super slow and boring Youtube tutorial video. Therefore, let me give you just a little treat about what you should be really careful about and what you would be better to know.
Image format! Image format! Image format! It should be the most important thing you should know when you start out. InDesign indeed can import many formats for images that include JPEG, PNG, EPS, PICT, PDF, PSD and TIFF but you should know which format you need to use. If you want your work to be printed then you should make sure that they are in the acceptable format such as EPS, TIFF and PDF and stick with them.
Besides, make sure that your work is NO HIGHER than 100% of your size or you will be regret because they will be printed out as many separate papers. Normally, your printer will give you the measurements for the bleed but usually only 3mm or 1/8 inch should suffice. So, just set up the margins, bleed and the paper size for your work at the very beginning.
And to be safe, try to avoid JPEG because it is the format that is set as low-resolution. Then you should check that your work have the resolution of 300 PPI (pixels per inch) and always double check that the work is saved as CMYK color mode. Most of the images are set as RGB color mode at the beginning but after editing, we would better set them as CMYK because it is the most stable and color mode for printing.
I believe that most of handy and effective tips usually come from people’s personal experience. But if you still are looking for useful library of skills. I recommend Adobe InDesign CC for tutorials. They provide official key techniques for beginners.
