Photopolymer plates production by Flexo24 v.2 software
Photopolymer plates production by Flexo24 v.2 software.
Photopolymer plates: optimization for the production of printing plates thanks to the latest release of our Flexo24 software suitable for the online flexographic prepress.
Flexo24 released the new software for flexo pre-press to produce photopolymer plates and to receive the analysis of your PDF files online in real time. The 2.0.1 rel 22 version adds new, improved features to the existing functions, see this article: Flexo pre-press for the PDF: how to optimizing?
Save your configuration in real-time.
Once the features from the configurator are selected, you can save them for a quicker response next time. Here is a video explaining the new SAVE function:Flexo24 improved the analysis of your PDF files by detecting additional features through the new release of the real time software for flexo pre-press.
All these features DO NOT prevent the file from being valid for production in case of mismatch. Here are some suggestions on how to improve the result of your pre-press:
- processing steps’ inside the PDF
- Dot gain compensation curves (DGC) already applied
- overprinting white: fine lines
- overprinting white: filling, graphic elements
- JPG images
ProcessingSteps.
Thanks to the new software release, these processing steps for the production of plates are detected if they are already contained in the PDF file uploaded through our configurator.
Here is the message that you get:
ATTENTION: PDF contains Processing Steps according to ISO 19593-1:2019.
To avoid undesired results, these are not processed by our RIP systems. If you need these features to be processed, we suggest to apply them to your job before uploading the file: it’s up to you.
NOTE: you can always ask for a consultation with one of our Flexo24 experts to optimize your PDF file, just order the PDF check.
Dot gain compensation curves (DGC).
DGC is specific for flexo direct printing. The compensation curves optimize the sharpness of the printed results by adjusting the engraving values of every single dot on the printing plate.
The dot gain created by the printing machine can be compensated with a DGC value from our Flexo24 configurator. Some PDF files might already be set with this value, i.e. with a dot gain compensation curve already applied.
If curves are already applied, the analysis of the file will display this message:
ATTENTION: PDF contains dot gain compensation curves.
To avoid undesired results, these are not processed by our RIP systems. If you need a DGC to be processed, we suggest to apply this to your job before uploading the file: it’s up to you.
Fine lines OVERPRINTING WHITE.
‘White print’, non-printing white area, or overprinting white creates some misunderstanding even among flexo experts in the field of the packaging design.
It is usually intended as::
- ‘non-printing area’ to make the color of the substrate (usually white) pop up,
- fine lines or graphic elements to be printed in white: this is a typical feature of flexo printing (white overprinting).
NOTE: in more complex flexo projects both solutions can be applied.
The new 2.0.1 rel. 22 version of the online Flexo24PDF software helps to optimize pre-press and displays the following message if any white line is detected::
ATTENTION: Fine lines OVERPRINTING WHITE detected in the PDF: these will not pierce through the other color separations/channels into the elements printed beneath.
As this feature might produce undesired results, it’s up to you to ensure that it is correctly managed.

OVERPRINTING WHITE: filling, graphic elements.
Our latest release enables the flexo pre-press operator to be warned about those graphic elements that are "white" filled. These graphic elements are most of all unexpected to produce correct photopolymer plates.
For the production of flexo plates on flexo systems it is required to be well aware of the ‘overprinting white’. To avoid any misunderstanding the following non-binding message will be displayed:
ATTENTION: Graphic elements filled in OVERPRINTING WHITE detected in the PDF: these will not pierce through the other color separations/channels into the elements printed beneath.
As this feature might produce undesired results, it’s up to you to ensure that it is correctly managed.
Embedded JPG images.
The PDF file that you want to upload can also contain rasterized, non-vector, JPG images. For flessography, we suggest to use images in other vector formats..
If the analysis of your PDF file finds any JPG images, the following message will be displayed:
ATTENTION: JPG images detected in the PDF.
As this is a compression format that makes images loose their quality, ensure that these are saved with a compression factor that does not affect the final quality of the printing plate.
Flexo printing systems are always improving by Flexo24.
“Innovating today means offering human technology, with solutions and tangible advantages for the packaging industry. The digital era is in full swing, and having just an original intuition is not enough. Expertise and professionalism helped Flexo24 to create the first B2B e-commerce for the flexo field, introducing constantly innovation and raising the service level.”
