Here is a copy of the Iproof post on another forum concerning the features of the RIP upgrade available for the Flexi-jet. I have asked a person using it ( I have never used it myself) and was told that this version can much more easily accomplish your desired results if you use the "print from" features.
Hello Flexi-Users,
I'm pleased to announce the release of PowerRIP Flexi-Jet version 7.4.4
And now available at
DTG Inks - Home
This version includes only two new features but one of them is a pretty powerful one. This version includes a new version of the previewer and a new "Print-From" feature which allows you to open the artwork, position it, create the underbase and preview it in the RIP without having to use PhotoShop, etc.
Unfortunately, version 7.4.4 is not free to current users. It is a chargeable upgrade. Although all new orders will be filled with version 744, existing users will need to pay a nomial upgrade fee.
Please Note: UNLESS YOU HAVE PURCHASED VERSION 7.4.4 IT WILL NOT WORK WITH YOUR CURRENT VALIDATION, IT WILL PRINT THE WATERMARK.
There is an addendum in the documentation section of the program group (start/programs/PowerRIP FlexiJet/documentatin) which covers the new Create-Job dialog.
==========================================
A little background...
There are two basic types of work flow when it comes to ripping. The "Print-To" RIPs like PowerRIP where you print "TO" the RIP from an application such as Photoshop or Corel. The other is a "Print-From" RIP where the user opens the artwork in the RIP, manipulates it and prints it from the rip application.
I've always been an advocate against print-from RIPs as I believe that the artwork should be manipulated in and printed from the application (Photoshop, Corel, etc.) as the RIP is and should be part of the printing process, not part of the artwork editing process. Indeed, a lot of print-from rips are that way because the developers simply don't know how to create a rip-to solution. Others were designed that way on purpose. It is no surprise then that because print-from solutions were so prevelant in this industry some folks became accustomed to having to open their artwork using the RIP.
As it turns out, however, there is one (and it's the only one I can think of) scenario where it is actually advantageous to be able to open the graphic in the RIP. This scenario involves white ink and transparency information. The one thing a print-from rip can do that a print-to rip cannot is recognize the color "transparent". This is because the transparency attribute disappears as soon as you print from an app (Photoshop, etc.) and all transparent pixels become the same as white pixels. So, transparency information cannot be used to auto-generate white ink in a print-to RIP. This was the main motivation for adding the "Create Job" feature.
You can open a file with a transparent background and PowerRIP can use the trasparency data to generate the white mask (white pixels will be printed in white and trasparent pixels will not be printed at all). It also contains other methods of white-generation. Although PowerRIP's print-to workflow has many different and powerful ways to generate white ink, both automatic and manual, the addition of the Create Job feature adds all the functionality of a print-from RIP including the ability to use transparency information. This should eliminate any argument against using PowerRIP versus some other software and some other printer as we now have "the best of both worlds". We not only added all the functionality of the print-from's out there... we went a couple of steps further.
There are a bunch of cool features such as the ability to export/import the auto-generated white mask. This will allow you to make changes to the RIP-generated white mask (I believe this is unique to PowerRIP).
