4. Transparent elements in your artwork 

Only applicable if your pouch material is Recyclable Transparent Plastic.

There are two ways how partial transparency can be used – your pouch is fully printed and only has a transparent window, or your pouch is transparent and only has some elements printed. In essence it is the same thing, but we recommend different approaches for easier workflow.

4.1. Creating a transparent window on mostly printed pouch

First, “Metallic/Transparent Elements” layer must be turned on.

In Metallic/Transparent Elements layer simply add
elements that must be transparent in your final pouch. It is important that these elements would have white colour (C0, M0, Y0, K0).

4.2. Mostly transparent background with design elements

Alternatively, your pouch can be mostly transparent with some printed elements. For that to work, all elements should have a white layer printed underneath it.

The simplest way to do it is to copy all your elements to Metallic/Transparent Elements layer and select their colour to be HPI-White. This colour is already available in the template.

It can happen that you need to create additional white elements (for example a rectangle under EAN barcode or QR code). You can do this by adding solid colour elements in the same Metallic/Transparent Elements layer and colouring them with HPI-White colour.
