Hello Publishers!
You may sometimes notice differences in the graphics in your original document and the document once it has been uploaded to Calaméo.
In this post, we’ll explain how to optimize your document so you can avoid this type of issue going forward.
The best way to solve conversion problems is to print your document to a PDF printer. A PDF printer is a virtual printer that creates a PDF file instead of printing to paper. The resulting document will be optimized for conversion in Calaméo. There are various PDF printers available. Some are fee based, such as Adobe Acrobat, but others are free, like PDFCreator.
We like PDFCreator and you can download it at the following address:
http://sourceforge.net/projects/pdfcreator/
Once you have installed your virtual printer, go to Printer -> Options:
Now, we’ll guide you through the settings in Options that will help you optimize your document.
To save time, you can directly download the PDFCreator Calaméo preset here:
To install it, run PDFCreator -> Printer – > Options -> Add Profile. 
Select the General Options tab:
As shown above, in the Compatibility drop-down menu, selecting PDF 1.3 or 1.4 will fix most of the problem you might encounter but you can go for1.5, 1.6 or 1.7 too if you want. By optimizing your document to PDF 1.3 or higher, you make sure that unsupported features will not corrupt your layout.
Select the Compression tab:
Set the image resolution to 150 dpi. A higher resolution will only increase the size of your document and will, in any case, be automatically resampled at conversion.
Select the Fonts tab:
If you are using non-standard fonts, you must embed them in your document so that our conversion engine has access to them when rendering your page layout. If this is the case, be sure to check the appropriate option as shown above.
Select the Colors tab:
Since the document will be displayed on screen, choose RGB color model in the drop-down menu, as indicated above.
Select the Security tab:
We cannot convert password protected documents. For this reason, we suggest that you do not select security options for your document.
Select the Signing tab:
As with Security settings, we recommended that you do not activate Signing options in your document.
If, despite these tips, you still have trouble with the conversion process, do not hesitate to contact us at contact@calameo.com
Happy Publishing!
