I made one simple example of print ready billboard design (4m x 3m) and I have some questions about it.
1.) In this example I used .jpg picture 7644x5000 and 96 dpi. I learned that for billboard in real size, raster image need to have at least 30 dpi. So if i resize this picture to 323cm x 211cm (and put it in the middle of billboard), it will have 60 ppi, which is enough for print. Am I right?
2.) Can I combine raster image and vector text in same design using Illustrator. I suppose yes.
3.) For large text I can use rich black and for small text k 100% black?
4.) When I design billboard I don't need bleed?
5.) I saw that many people suggest using of inDesign when combining vector and raster, but why i can't do it in Illustrator as well?
6.) When i convert text to outlines, I don't need to send font with pdf file?
7.) What preset should I use when saving pdf file?
I opened new document with 40cm x 30cm, 300 dpi, CMYK. Put the picture inside and some text with rich black. If I save it as .pdf and send it to print, what quality is it going to be? This is just an example and I'm not going to print this. :) Thank you.
