[muglo] Re: Ordering clip art--XS standard @72 dpi?

I included a file with that post regarding setting up a quartz filter compression option. Using your built-in quartz filter, you can compress a pdf file up to 90% without any apparent loss of resolution. It may sound a little complicated, but take it step by step. You will find it quite handy.

If you open the PDF in Preview, you can reduce the file size by doing a “Save As...” and choosing, appropriately, Reduce File Size from the Quartz Filter menu. Often, that will be fine. But the way that it reduces the file size is by saving all images as JPEGs of middle quality. Sometimes that quality will not be enough.

When saving JPEG files you are allowed to trade off low file size with increased quality. But there is no slider available in the Quartz Filter menu to increase the quality of the image.

The answer, it turns out, is in ColorSync Utility in the Utilities folder of the Applications folder. ColorSync Utility can create new Quartz filters. Open up ColorSync Utility and switch to the “Filters” pane. This will list all of the filters that you currently have available.

1. In the lower left, click on the “+” button. This creates a new filter.
2. Give the filter a name, and press return.
3. To the right of the filter’s name, choose the down arrow. A menu will pop up.
4. From the pop-up menu, choose “Add Image Effects Component”, and from that menu choose “Image Compression”.
5. Adjust the image compression Mode to JPEG.
6. Adjust the image compression quality however you prefer.
7. The next time you use Preview to “Save As...”, you'll have a new option under Quartz filters.

Filter while printing

You can also filter while printing, avoiding the need to re-open the PDF in Preview. When you go to print, pull down the menu just below “Presets” that usually says “Copies & Pages”. Choose “ColorSync”. Then choose the Quartz filter that you want. Once you’ve chosen it, you can also pull down the Presets menu and do a “Save As...” to remember these settings.
