#Pdfwriter distiller security driver#Applications that do not produce Postscript directly use the AdobePS printer driver to generate the Postscript. The creating application firstly creates Postscript. Now we are using the Distiller as the tool to create compact PDFs, its time to understand the process it goes through to create the resulting PDF. As Zapf Dingbats in installed along with Acrobat Reader, the local version of the font will be used. If Zapf Dingbats has a similar character or mark, use that glyph instead. Widget style fonts such as Wingdings et al are ok, but each time they are used, the Distiller has to embed the characters into the PDF. For every font or typeface used, Acrobat may (depending on the settings) embed more font information. Try to minimise the number of typefaces used in a document. Just reusing the character and referencing a typeface will take a byte. If it is used again, the whole shape is described again – this may take many bytes to do. When creating PDFs each time a character is used in the document there is a vector shape describing that glyph (character). Usually, this is done to reduce the need for a font to be sent along with a document. Applications such as Illustrator and Freehand have the ability to convert type to outlines. ![]() This is especially the case with elements such as corporate logos: they are usually available in vector format, and are used many times in a PDF. As images take the most space in a PDF, use vector graphic elements whereever possible. So try to keep the source images and colour definitions in RGB. Firstly, images in the CMYK colour space takes extra disk space, contain less colour information (technically: it has a smaller colour gamut) compared to RGB and the the Distiller will convert from CMYK to RGB anyway. I recommend we use the Distiller as our preferred process/path for creating a compact PDF. This state is then easily represented in PDF. It takes the Postscript generated by the application and interprets it leaving the resulting images, text and graphics in an internal object-based state. The Distiller, at its core, has a Postscript engine. Why does the Distiller produce a smaller PDF? Postscript is targetted at printed output from low end laser and inkjet printers to very high quality printed output. #Pdfwriter distiller security pdf#PDFWriter: Fonts 4.5%, Images 92.3% Ībove: Tools>PDF Consultant>Audit Space Usage Report for PDFWriter created PDF Looking “inside” the PDF using the Acrobat 5.0 “PDF Consultant>Audit Space Usage” reveals the differences when comparing the two files:ĭistiller: Fonts 9.5%, Images 68% Ībove: Tools>PDF Consultant>Audit Space Usage Report for Distiller created PDF ![]() PDFWriter is no different: we are asking the application to generate a representation of the page using the operating system’s internal graphics perfectly tuned for screen output – but no so for printed output. However, the distance you travel is very different. Using either path you will arrive at the destination. You can travel from Perth to Sydney the quickest way – or – via Darwin. Why is the PDFWriter’s PDFs larger? Isn’t it the same file? Well, yes – but the path taken is different. ![]() Source Microsoft Word 2000 Document: 221184 bytes In both instances, I have used JPEG-medium settings for image compression. Using a baseline file containing one graph (vector graphics), one image and text using Times New Roman (Truetype) – we can compare the file size of Distiller vs. Quickdraw and GDI is not as accurate as Postscript with positioning. The PDFWriter takes GDI (Windows) or Quickdraw (MacOS 8/9) printer calls and converted these into a PDF file. This would require a long, and indepth study of PDF as a file format and squeezing every last byte, redundant space and element from the file.Īcrobat 3.0 and 4.0 installed a printer called ‘PDFWriter’. #Pdfwriter distiller security how to#This article is not going to describe how to make extreme PDFs. Whilst making PDF is relatively easy, making a small, compact and efficient PDF takes a little setup and thought. Sometimes even at work our access to the internet is throttled by slow modems, slow proxy servers – or god forbid, both. #Pdfwriter distiller security download#The web, however, is not a fast, high bandwidth unlimited download environment many of us experience at work. Due to the ease of “printing” to a PDF generating Printer such as Distiller or PDFWriter rather than totally regenerating the page in HTML or SWF - and also not to mention the cost of the Reader (free!) - placing PDFs Forms, visually rich brochures and long documents are presented in PDF form. #Pdfwriter distiller security portable#Portable Document Format (PDF) files are a defacto standard for publishing complex documents on web sites.
