Image quality

22/08/2008

Use the image placeholder in your template to set the required quality that the user uploaded images should have. User uploaded images will be downsampled to the parameters of the image placeholder.

Resolution

Depending on the purpose of the template, the resolution of the image placeholder can vary. The most common standards are:

  • Web-to-Web templates (ex. Web banners) should have 72 DPI images
  • Web-to-Print templates (ex. Business cards) should have 300 DPI images
  • Large Web-to-Print templates (ex. Posters) should have 96 DPI images

Example

A business card that contains a photo should have a image placeholder whose parameters are set to 300 DPI of resolution so that if the uploaded image used to replace that placeholder is larger than needed, it will be downsampled to 300 DPI.

Image editing

You can use the images in your images library to select a collection of images for your customers to choose from for each of your templates, instead of uploading their own. To edit the images located in your image library use the image editing tools.

Color mode

The uploaded image is converted into the color mode of the placeholder. Depending on the purpose of the template, you can set the placeholder to be in RGB color mode (for screen) or in CMYK color mode (for printing).

Note. You can force RGB or CMYK in the PDF settings, which overrides the colour mode when generating a PDF file. Learn more about it here.

File size for high resolution images

Most likely, the bulk of your file size is taken up by images. You can reduce the template’s file size without compromising the quality of the final product.

Example

A full page magazine ad template may contain high quality images. If you use high quality images as placeholders, the size of the template file will be large. Keep in mind that the image placeholder is for setting the required parameters for the uploaded images.

  • Using simple but informative placeholders will reduce the file size of the template.
  • Decrease the size of the image used as a placeholder by decreasing its JPEG quality.
  • Create a preview template and replace the placeholder images in the printing template with blank images of the same resolution because no one will see the placeholders from the printing template anyway.
