One big reason in the past to decide for RIP's was the number of profiles available from the vendor or the media supplier. This reason is obsolete because of the profiles are working with every RIP which have a driver. so the "quality" of the profiler module is not a key feature too.
We have tested and we support the following RIP's with Latex 360 (just my opinion):
FlexiPRINT - for my opinion the best driver for the Latex 360 up to now. Very easy to use. Profile management (deleting, renaming, cloning and so on) and downloading from the profile database for upload in the printer is possible directly from the software. Software synchronizes Media Type AND Media size. Possibility of up to 50 Print Queues with different presets, and presets can be saved on the fly from configured files. Editor with very comfortable possibilities to add cut contours to graphics and pictures. FlexiPRINT HP Premium Edition available for little money for the Latex 360 too, as a HP-Edition of FlexiSIGN-PRO (or a regular FlexiSIGN-PRO) too.
Onyx Postershop/Productionhouse - works fine with the Latex 360. User interface not very intuitive, some things really awkward. Swatchbook-functionality in colour replacement to find matching colors is really cool. Not synchronizing media size. Not cheap. Great functionality for automate contour cutting for example together with Summa OPOS Barcode (assigning contour properties to contur names etc., no need to send the jobs manually).
Ergosoft Posterprint - works fine with the Latex 360. Little bit awkward to switch from media to media because of a separate printer environment needs to be configured for every media.
Caldera - works fine with the Latex 360. Until now no way found to let caldera sync the files from the printer automatically, from my sight everytime when new profiles are created or downloaded to the printer a sync button have to be clicked in easy media. cool tiling tool (second best I've ever seen).
SAi Pixelblaster - currently tested the mac-version only, and just a few tests. A lot of functionality for layouting, serializing and automate prints. Floating licence. Best tiling tool I've ever seen. Currently not certified from HP. Expensive.
