I am a firm believer in RIPs, with reservations. If you are going to use a desktop printer I don't think a rip will be of any great advantage to you. If you are going to the wide format printers then a rip is most certainly useful. RIPs are designed to do several things for you. They allow you to process your files a lot faster then your OEM drivers. When you are printing with a wide format printer you would normally be larger images or multiple images per file. Lets say you have 4 images of 30 megs. each, that's not unusual. That is a raw file to the printer of 120 megs. When this file is ripped and sent to the printer the files grow to about five times their size. Most OEM drivers can not handle files this large. RIPs are designed to handle these files with ease. Also with rips you can put multiple sized images in a file plus multiple images. With OEM print drivers this is almost impossible unless you set up the files in your photo editing program. Another thing most RIPs allow your to do is color management within the RIP. If you run a print and the colors are not quite right you can go into the RIP edit program and tweak each image. The RIP also allows for rotating the image so you can get the best fit with the sheet your are printing. This is a rough explanation of RIPs. There may be many more things a RIP will do for you, but these are some of the things I have done with RIPs. As for the best RIP. I don't think there is any one RIP that is best. It all depends what you want to do with it and how much you can afford to spend. You will find RIPs from around $500.00, with very basic capabilities, to full blown RIPs for up to $5000.00. As I mentioned above I am not sure a RIP is needed for desktop printers. Most of the time you are not doing multiple images on a desktop sheet. You would normally do your color correcting in your editing software. The cost of doing a reprint on a desktop machine is not as great as having to redo images on a wide format machine. It is also much easier to to reprints on a desktop machine than a wide format machine. There are others on this list who will have much more input than I can give you. I would go on a search and find all the companies who supply RIPs and get a good idea what is available. Then come back and we'll see if we can help answer any additional questions you may have.
