Maybe that was the wrong title. I've been using CorelDraw to design my miniatures and when I publish them to PDF, I get a variety of results. Regardless of whether you use or have used Corel, what PDF settings do you use in your program? RGB or CMYK? Compression, if so what type and at what setting? Do you convert your designs to a JPEG (or other file type) first before you PDF? Bitmap Downsampling settings for Color, Grayscale, and Monochrome? ASCII 85 or Binary Encoding? I realize that these settings may be unique to or uniquely named in CorelDraw, but any insight would be helpful. I've been experimenting with the different values, but there are just so many options. Thanks! edit: I just found this thread and I'll use this as a starting point, but any other insights would be helpful.

I use RGB. The color palette seems to transfer better. I had problems with the web and CMYK. I use Zip or loss-less compression. It makes it the smallest without killing quality. I use PNG images initially, placing them out in the PDF.
I've actually been using a program called Scribus. It is a simple PDF creation tool.
Hope that helps!

I convert the figs to 300 dpi images, text I leave alone. I save as PDF, 300 dpi, no compression, RGB
These are the only setting where I can get total accurate reproduction of what I designed.
For bitmap formats, Adobe designed the PDF format to work best with TIFF format images ,although most any format will work.
It is important to work in the same resolution that you export the PDF as, work in 200 dpi if you plan to export in the res. PDF resolution conversion sucks. JIM

I've actually been using a program called Scribus. It is a simple PDF creation tool. Does Scribus let you combine individual, single page PDFs into one PDF? If not is there a program out there that does? What about Microsoft Publisher (I haven't found a use for that program yet...)? When I've been converting by documents to PDF in Corel, I only get the first page. This could be user error...

I tend to save my finished Photoshop images(once flattened as 300 dpi cmyk Jpeg) as a Photoshop PDF, then use Adobe Acrobat to convert them to multi page pdf. I think I may be pretty lucky as we have the latest version of this at work...

Thanks for the input. It turns out that my PDF'ing problems were user error as I had missed one check box. "User Error"="I am a tool" My settings are now: Bitmapped Objects, 300 dpi, Vectored Text, RGB, Zip compression.

And the discovery continues... Today I noticed that when I convert to bitmaps, I have not had the box for transparent backgrounds checked. Testing it out, it cut my file size by THIRTY PERCENT! This makes sense as I don't need all the white spaces bitmapped. It doesn't seem to alter the quality either. Is there a downside to transparent backgrounds that I am missing?

The file size will depend not only on resolution and size, but what file type you save as well. Bitmap has the largest file size of any format, but also does not have any compression at all, it is exactly what it is. Other formats compress to a lesser or greater degree with JPEG being variable for quality.
Adobe PDF's love the TIFF format, and were programmed with built in compression/decompression engines in the free PDF reader.
All that really matters is that it's a format you can work with, and the final results look good, who cares about the rest. I figure as long as the file isn't like 100 Meg, then things are good. JIM
