Default Word 2010: creating vector pdf + issues missing figures in pdf

The word file of my PhD thesis needs to be converted into a PDF. It contains lots of drawings of chemical structures created in ChemOffice. I copy and paste them in word where they are an embedded object: if I double click the structure, ChemOffice opens and I can edit these vector drawings.

Strangely, some figures are not printed when I print (to physical paper or using CutePDF write or acrobat distiller), whereas other figures that are created identical are fine.



It gives me quite a headache as I have literally hundreds of figures in my thesis and they can't just be omitted. Attached is a word file and two pdf's: one created with CuteDPF, the other created with the save as => pdf in word. The latter seems to work (haven't checked all 300+ pages), however, it rasterizes images and quality is lost.

Second: it seems that also acrobat distiller rasterizes these vector drawings, which is a pity due to file size and loss of quality. Is there a way to convert the word file into a descent pdf with all the vector information intact?

AFAIK you cannot prevent the rasterization of the images - if for no other reason than that's what the colour one already is (it's in PNG format). However, if you configure Word to not compress pictures in the document (File|Options|Advanced>Image Size & Quality) and, when you save to PDF, click on Tools>Compress Pictures>Use document resolution, that should maximize the image quality.

FWIW, when I print to PDF using Microsoft's built-in PDF printer in Windows 10, the output is of far higher quality than your save_as pdf. Of course, you don't get any bookmarks or links when you do that...

That colour image is indeed a PNG and in my original file compression is turned off. For convenience and size I decided to turn it on for the file posted here.

No bookmarks etc is not an issue at the moment as it first needs to be printed. Publishing online with a pdf that has bookmarks is of later concern.

The windows 10 pdf printer does sound attractive, but I'm using windows 7 and office 2010. I can install windows 10 in a virtual box so I can create a pdf there, but I need to use office 2010 because office 2016 adds a ; to my chemical formulas created with an equation (for example Co2(CO)8 where the 2 must be in subscript and then a 0 must be directly above the 2). Can you install office 2010 in windows 10?

Yes, I have a Win 10/Office 2010 combo on one of my laptops.

Great

The software used to create the black&white drawings (not the color png) allows saving in quite a lot of formats.

Would it be possible to keep them as a vector when using one of the formats that chemdraw supports? Attached is a screenshot.

You might try Windows Metafile or Enhanced Metafile. Microsoft has recently deprecated EPS support due to security issues, so you probably won't want to use that. If ChemDraw functions as an Office plugin, you may find Word can open one or other of the ChemDraw file formats. Check under Insert|Picture and look at the list of file formats supported.

Nice EMF seems to work.

If I want to use that format, several hundred chemdraw files need to be openend, saved as emf and inserted as a picture in my thesis file...

Borrowing a Win 10 PC might be simpler...

It is, and I can easily run a virtualbox with win 10, but the EMF output is 100% vector and looks very good.

I replaced all the vector figures for EMF ones. Strangely, when converted using acrobat pro, in the pdf the lines in the figures are vector, but the text characters have been converted to pixels. To make it extra clear, I converted one page with a low resolution jpg setting for pixel data. One of the EMF files is attached (as a zip) as well.

Any ideas how to convert to pdf with everything as vector?

When I opened your attached emf file, I found no vector data - only raster.

If you choose insert => picture and insert the attached emf file into a word document, does it then change into raster data?

Strangely, if I convert the word file in acrobat pro by choosing create => pdf from file, the figures do look like vector data, but not all layouit is corectly converted & one cannot choose the compression for the png's which are also in the word file.

Changing the insertion method isn't going to change the emf's content - which is raster.

How do I see/know that the EMF file is a raster file? (just curious)

I simply opened it in IrfanView; any other graphics app that supports EMF should do, though.
