Affinity Designer lets you access and modify your document setup at any time. This setup will have been chosen previously when creating a new document.
To modify your document setup:
From the File menu, select Document Setup.
The settings are as follows:
Type—Select the aim and deliverable for your project (for quickly populating settings below). As well as print (press-ready CMYK), you can work to specific Photo print sizes, specific Web screen resolutions, and with the Devices option, design to iPad, iPhone, Apple Watch and Nexus document specifications.
Page Preset—Offers sizes for UK/US print, photos, screen use, and mobile devices. A Custom option indicates if your page is using non-standard page dimensions.
Document Units—Displays your rulers and object dimensions in pixels, points, picas or using physical measurement units.
The dialog is split into separate tabs which let you customize your current preset or apply more advanced settings.
Dimensions—Change these values to make a custom page size. (An alternative to selecting a Page Preset size above.)
DPI—Sets the resolution of your document. For example, for professional print quality, set your resolution to 300 dpi.
Portrait—Uncheck to present your document in landscape orientation.
'Actual Size' Zoom—Sets the device which is mimicked when presenting the document at 'Actual Size' (from the View menu). This option is only available when the document units are set to Pixel or Points. Select from the pop-up menu.
Click Object will Rescale to increase/decrease object dimensions in relation to a change in Page Width and/or Page Height.
Use Object will Anchor to Page to keep object size unchanged when changing page size.
Anchor point—controls the anchor point of objects as the page is rescaled (when Anchor to Page is set).
Resample lets you control how objects are resampled when Objects will Rescale is set.
For Color (management):
Color Format—Sets the color mode to RGB or Gray (8 or 16 bit), CMYK (8 bit), or Lab (16 bit).
Color Profile—Sets the color gamut for the previously chosen color format.
For applying a different color profile, Assign adopts the new profile but leaves the values of the colors/pixels as is. Convert converts each color from the old profile to the new one—color/pixel values may change as a result.
Transparent background—Check to set your page background to be transparent.
Include Margins—Check to switch on page margins.
Left Margin, Top Margin, Right Margin, Bottom Margin—Sets the printer margins, showing as non-printable blue lines. Click Retrieve Margin from Printer to use your default printer's settings.
Left Bleed, Top Bleed, Right Bleed, Bottom Bleed—For professional printing, bleed extends the printable area beyond the page edge to allow artwork to be trimmed.
