To begin a new blank project, click on the Start Zone icon
on the Create screen
or select New Project from FILE menu item to launch the editor for a new project.
The FEATURED tab will appear when your software is activated, and show either commonly-used generic sizes, or your album manufacturers presets (e.g. YearbookFusion users)

Depending on your license type, more or fewer settings will be available, related to your output limits.
An Essentials and Enhanced user will not see form factors that exceed their license limits (eg. no album 2-page spreads will appear); a YearbookFusion user most likely only see their manufacturer's form factors, whereas an Extreme user will see all options.
This guarantees that you will not be able to select a canvas size that you will not be able to output or that will be rejected by your album manufacturer.
The GENERIC tab display commonly used-page sizes, categorized under the type of output (Album, Digital, Sheet, or Specialty).
The MANUFACTURERS tab will display available sizes for album or printing companies who have provided information on their product lists to LumaPix.
If you need a custom size that is not available, select the CUSTOM button, which will open the Canvas Settings editor.
You can also create your own Form Factor, which can be accessed from the User Preset tab, which will appear next to the Manufacturer's tab.
A new blank page will open with your chosen page size. You can change the page size, guidelines and page type at any time during the creation process.
