Low Res Images FrameMaker

Brief Description



Resolution refers to the number of pixels in an image. Resolution is sometimes identified by the width and height of the image as well as the total number of pixels in the image.

Image resolution or "DPI" ("dots per inch", also called "PPI" or "pixels per inch") determines the number of pixels that a digital image can contain and as such the depth of quality and size of the file. The more pixels an image can contain, the better quality it can be but also the larger the file size. It is important to understand how resolution affects image sizes - in print, the resolution does not affect the image size, but on screen, resolution can have dramatic effects on the image size.

What your issue is

Fuzzy images in PDF files created from FrameMaker due to image dpi setting

How to fix this issue

(You are welcome to edit this)

This issue can occur if the dpi settings for the images are not evenly divisible into the printer's dpi.

To resolve this issue, make sure the dpi setting for each fuzzy image is evenly divisible into the printer's dpi. Solution Details

1) Click 'Start' on the Windows taskbar, point to 'Settings', and then click 'Printers'.

2) Right-click the printer you want to use, and then click 'Properties'.

3) Click the 'Graphics' tab.

4) Note the dpi listed in the 'Resolution' box.

5) Switch to FrameMaker.

6) Click an image that is fuzzy in the PDF file.

7) On the 'Graphics' menu, click 'Object Properties'.

8) Make sure the dpi listed in the 'DPI' box under 'Scaling' is evenly divisible into the printer's dpi.

 EXAMPLE: If the printer's dpi is 600, make sure the image's dpi is 75, 150, 300, or 600.

 NOTE: To change an image's dpi setting, click 'Set dpi', specify the setting in the 'Imported Graphic Scaling' dialog box, and then click 'Set'.

9) Repeat steps (6) to (8) for all other images that are fuzzy in the PDF file.

More details

If you are creating a PDF in FM, you should go to Save As or Save as book (single file or book) and in the PDF for Selected Files, change the Default settings to say the High Quality Print.

When an image is imported in FrameMaker, FrameMaker asks for DPI setting which defines the resolution at which the image should be displayed when published. In other words, it asks the user to provide the setting to render each pixel of the image on the computer screen. If the screen resolution is 96DPI and the image scaling setting is also 96DPI, one pixel of the image is mapped to one pixel on the screen. If the image scaling setting is set to 192DPI on the same screen, 2 pixels of the image is mapped to one pixel on the screen thus scaling down the image. When this image is converted to PDF through distiller, the entire image is scaled down to display it at a smaller size. However, there is no loss of pixel information. The entire pixel information is preserved so that when the PDF document is zoomed in, the pixel information is used to scale up the image thus maintaining the quality of the image. A high DPI value (say 200DPI or 300DPI) is recommended for good print quality on paper.
