This example describes how you can render the personalized design with imposition, i.e. copying an artwork multiple times on a larger sheet.

To produce imposition, it is necessary to prepare a template in Adobe Photoshop, where smart objects will be placeholders for inserting graphics. For more details about creating such templates, refer to the Template-based imposition topic.

First, let's split our goal into simple operations from getting a design from the project to cleaning up the pipeline and updating the project.

flowchart TB t1(Getting a design from order) t2(Rendering the design) t3(Adding crop marks) t4(Producing imposition) t5(Finalizing) t1-->t2 t2-->t3 t3-->t4 t4-->t5

These operations are performed using the following tasks:

• extract-project-design
• render-vdp-hires
• draw-crop-marks
• produce-imposition
• finalize

Artifacts are conveyed between these tasks as follows:

In this example, it is assumed that you have placed a bc-8up-letter.psd template in the Images > imposition folder. For reference, you can download and unzip this template.
