What Is PostScript Fill in CorelDRAW?

PostScript fills in CorelDRAW are advanced, mathematically generated texture fills that allow designers to apply intricate vector patterns to objects without sacrificing image quality. This article explains what PostScript fills are, how they function using algorithmic code, their key advantages over standard raster textures, and the steps required to apply and customize them effectively in your vector design projects.

Understanding PostScript Fills

A PostScript fill is a procedural pattern generated through the PostScript page description language rather than a static bitmap image. When you assign a PostScript fill to an object, CorelDRAW uses mathematical formulas to render complex textures such as crosshatching, bricks, reptile scales, bubbles, and woven patterns.

Because these fills are generated via vector code, they are resolution-independent. Unlike standard bitmap texture fills, PostScript fills retain crisp, sharp edges at any magnification level or output size without pixelating or blurring.

Key Features and Advantages

  • Infinite Scalability: Because they rely on vector mathematical descriptions, PostScript patterns scale cleanly for both small desktop printing and massive wide-format signage.
  • Deep Customization: Each PostScript pattern comes with unique editable parameters. Depending on the selected pattern, you can adjust properties such as line thickness, frequency, density, pattern scale, angle, and foreground/background colors.
  • Low File Overhead: Procedural fills store code parameters rather than large pixel-based image files, keeping CorelDRAW document file sizes relatively small.

How to Apply a PostScript Fill in CorelDRAW

  1. Select the Object: Use the Pick Tool to select the vector shape or text you want to fill.
  2. Open the Fill Settings: Double-click the Fill icon in the Status bar at the bottom right, or press F11 to open the Edit Fill dialog box. You can also select the Interactive Fill Tool (shortcut G) from the toolbox.
  3. Choose PostScript Fill: In the fill type options at the top of the dialog, select the PostScript Fill button.
  4. Select and Adjust a Pattern: Choose a pattern from the preset dropdown menu (such as Basketweave, Birds, Bricks, or Honeycomb). Modify the available numeric parameters to change the appearance, scale, and density of the design.
  5. Apply: Click OK to render the texture inside the selected boundary.

Display and Output Considerations

Because rendering complex PostScript mathematics can demand significant processor power, CorelDRAW may display a simplified preview or a crosshatched placeholder on the canvas depending on your display settings. To see the full visual representation on your screen, ensure your view mode is set to Enhanced or Simulate Overprints under the View menu.

When sending the document to print or export, PostScript fills output best on PostScript-compatible printers or when exported to PostScript-native file formats, such as PDF or EPS. If exporting to formats that do not support procedural PostScript code, CorelDRAW automatically rasterizes the fill according to your document's rendering resolution settings.
