swissQprint UV inkjet printers are capable of impressive relief and textured printing, offering a range of capabilities that cater to the demands of various industries. These printers are recognized for their proficiency in creating layered relief prints, which open up a realm of possibilities for signage, decor, wood printing, and more.
How is it done?
Capturing the Original Artwork: The first step in creating layered relief artwork for printing is to obtain a highly detailed 3D scan of the original artwork. The Metis 3D scanner and similar devices use various technologies to capture the physical details of the artwork. These scanners record the surface geometry of the object, including its texture, shape, and depth.
The data collected by the 3D scanner is processed to generate a digital 3D model of the artwork. This model contains all the surface information, including variations in depth and texture. The resulting 3D model serves as the foundation for the relief printing process. To prepare the artwork for relief printing, the 3D model is further processed to create a relief map. This map represents the depth and texture information as grayscale or heightmap data. In this map, lighter areas correspond to shallower sections, while darker areas represent deeper or textured regions.
Once you have your artwork you can begin the process of processing it through your PrintFactory RIP and sending it to the printer. You can open the file in Editor to gain a better understanding of how each page in your artwork is applying a varying % of ink in each pass/page.
The example artwork available at the link and pictured above contains 7 pages, the first 6 creating the build up of layers and the final 7th page containing a flood White undercoat followed by the full color final layer. This is a typical relief print artwork, usually with multiple pages where the final page will contain the White undercoat and the final color layer.
Setting up the job in PrintFactory
1. Open the multipage PDF in Layout, and it will appear with pages randomly arranged on the canvas, similar to this:

2. Go to Alignment and nesting, choose "Job Order - Upright" and click Nest. This will then arrange the pages in the order they are in the PDF:

3. Turn on Split into Individual Pages, this will arrange each page of the PDF into it's own page in the job:

You can now see the print order of the layers. In the screenshot above, the bottom page will print first, and the top page will print last. For this particular artwork, the print order needs to be reversed. To ensure the pages arrive in the correct sequence at Lory, you may need to manually reorder them in the job list. To do this, disable "split into individual pages" and then go to your job list and manually drag and drop the pages to reorder them:

After reordering the pages in the job list, you can click 'Job Order – Upright' and then "Split into individual pages" again to update the nest so that the page order matches the new sequence:

4. Turn on "Multipage to Multilayer" - This ensures that your multipage job is sent to the Lory DFE as a single multilayered file, with each page stacked vertically as separate layers. If this option is not activated, the pages will be arranged side by side rather than on top of each other, an output format that is unsuitable for relief printing:

5. Activate your Layers - Depending on the number of pages in your job, you need to activate the corresponding number of Layers. So if your job has 7 pages, you need to turn on 7 Layers:

6. Submit the job
