Does anyone out there have any suggestions for me... I have a Roland Color Camm pc 60 and have good results with it especially when printing a file I have created in signlab my trouble comes with imported images..... what format supplies the best results jpeg.? bmp? I have different results all the time ... sometimes good, other times very pixely (is that a word?) I know it's not a high end machine but I really think I just need to understand my file resolution better. Advice?
Thanks

Hello, I imagine that all of the files that you have created have all be a vector image which means that the image has been mathematically created with curves and lines. These types of files can be increased in size to infinity and will not look pixilated. The other file types that you just mentioned, are bitmap file which are composed of tiny squares of color that make up the final image. When you increase the size of the image, the pixilation you see are those pixels. I imagine that when you receive these files from other people, you then increase them in size which will produce the pixilated look. You best beat is to always ask people how are supplying you with file for a vector format such .ai (Adobe Illustrator), .cdr (Corel Draw), or .eps. If you have to go to the bitmap files, see if you can get a .tiff which are general less compressed (pixilated) than any other file format. If you really want to get complex there are ways, i know in Photoshop (I am sure there are ways in other programs, maybe even Signlab, but I do not know how, so I will stick to what I know) to artificially enhance the number of pixel, and cleaning up the file a bit. It will still look pixilated (depending on the size you are increasing the original picture it may still be really bad)(or how much time you put into the image in Photoshop), but it will look better. Hope that helps a little bit. If you have any other questions, feel free to ask!

Since the color-camm is a printer, the question of raster image is correct. You need to know what file formats your program accepts. Most do include bmp & jpg. The main difference between the two is that photo quality will suffer if you use the jpg. This uses what is known as a lossy format that tosses out pixels it thinks you won't need after you uncompress what the jpg file compresses. Another form of raster image to try would be a tif, not to be confused with ttf. Many people prefer tif over the other two mentioned. There are others that can be used but your software will determine which can or cannot be used. Good luck.
