The images print corrupted or TrueType fonts print blurred

Problem

Your labels print images print with blurred edges or the filled areas are not consistent with black color.

Solution

Thermal printers print images in black and white (B&W) mode. If you use color or grayscale images on your label, NiceLabel drivers convert them in B&W before printing. The process is called dithering and it prints pictures suing black and white dots, creating the illusion of shades by varying the pattern of dots.

The default dithering mode might not be the correct one for your images. You can select among different dithering modes or disable dithering.

Options in NiceLabel Designer:

You can change the dithering mode per label or individually per each Picture object on the label. 

  1. Select the Picture object in your label.
  2. Open the object properties.
  3. In Style tab, select the Dithering type.
    When you select "Printer driver default" your printer driver settings apply. Read the next paragraph for details.
    When you select any other dithering option in the list, NiceLabel Designer applies the selected dithering type.

To change the dithering mode for the entire label (NiceLabel printer driver will do the dithering), do the following:

  1. Open your label.
  2. Make sure you use NiceLabel printer driver for this label.
  3. Click the Printer properties button on the left side of the selected printer name in the bottom part of the designer window.
    The window with printer settings opens.
  4. Click the Graphic options tab.
  5. Change the Dithering level to suit your needs. 
    Clipart level usually yields the best results.

Workaround

You can convert color images to B&W with graphic software like Microsoft Paint or similar.
