Until now, all print files generated by the system have been fixed at 300dpi - with a recommended maximum size of 1000 x 1000mm. For products with a larger print area than that, a workaround was put in place whereby you had to reduce the mm size to get a 300dpi file to generate, then print at a lower DPI to match the full print size in mm.
Utilising the Variable DPI feature, it is now possible to manually set the DPI value against the print area of the product on CPP, allowing you to successfully generate larger format files at lower DPI settings. This is recommended for any product that is larger than 1000mm in width or height. It is also possible to set variable dpi against a Print Area Layout, if you need to merge multiple files together.
Important Note: Variable DPI is currently only supported in 2d with ACP3 - your Output Type must be set to Raster Alternative. It also requires a custom config setting to enable the Variable DPI feature in the App - please liaise with your Project Manager at Custom Gateway for more information, or request these options by emailing firstname.lastname@example.org
How Do I Set It?
1) Access the CPP using this link:
This is our updated V1 interface that contains the new variable DPI feature. You can log in as normal to access your products.
2) On your product setup, access the Print Area, and change the dpi value via the Print DPI field:
3) Open the Print Test facility > ensure that the 'Use Product State' option is enabled, then start the test.
4) Add personalisation then Click to Add to Cart. The system will generate an example file at the specified mm and DPI size. Depending on the size of your print area, this may take several minutes. The screenshot below shows the file in Photoshop, at the specified resolution and mm size.
