when doing your artwork, You have to ask yourself three questions:
What is the printing process that will be used for production?
If the process will be silk-screen, dye-sub, or individual color foils, then you will want to limit your colors because colors=money, plus the more colors you add, the greater likelihood of mis-alignment. Also, you won't be able to do any shading. You'll want to use Pantone Colors, so you'll know what to expect when printing is done.
If it is on a CMY machine (commercial production equipment: news press, package manufacturing), up close, you will be able to see the individual color dots, and shading will vary depending on the quality of the machine.
For stuff like marquees and bezels, they can be done on "regular" large format ink jets. Pretty much unlimited colors, and shading isn't an issue. Of course this depends on who is doing the printing, and what equipment they are actually using.
What will be the final production size?
from Mamemarquees:
"Artwork you create must be the correct size and it should be at least 200dpi, but 266-300dpi is preferred. Leave the document in RGB mode which has a broader color range. Do not create a file in a lower dpi and then convert it to 300dpi, this only makes the file bigger and does not enhance the resolution. It will still come out blocky and actually worse then if you left it at a lower dpi. Start creating at 200 or 300 dpi at full size, in other words, if you are creating a 300dpi marquee that will print at 26x8” create it at that size."
Did he fire six shots or only five?
Do I feel lucky? Well, do ya, punk?
I felt lucky, but I wasn't. Or at least completely...
When I printed out my marquee and CP, the resolution was a little on the low side, because the tiling image I was using for my plaid was just a little gif I found online. I knew the Marquee would be okay, because it was being printed on a large format ink jet. It actually worked to my advantage that the resolution was a little on the low side, because it made the plaid appear to have stitches, instead of smooth computer generated artwork.
On the other hand, my original CP was printed on styrene, on a CMY machine. Because it was a different process and different color profile, the colors did not match. Also, because of the design limitations of that machine, my shaded areas were banded, not smooth gradients.
I kinda lost my way here, but I think what I'm trying to say is: it only needs to be vector if its going to be big. Also, know what your color limitations are.
