Crop package in a document with TikZ graphics

Question

My Problem Briefly

I've created an address book for my son's kindergarten using XeLaTeX. I used TikZ for creating the headers and footers and some other graphics. The book is in DIN A6 format. The printer asked me for crop marks since she will be printing the pages in a larger format and then cutting them down to DIN A6. When I use the crop package (e.g., with [cam,a5,center]) the TikZ graphics, which are positioned with coordinates, are misplaced since their coordinates then apply to the physical page size specified in the crop package options.

I am using Texmaker and MiKTeX 2.9 on Windows 7.

One Possible Solution: I could "simply" adjust the coordinates of all the TikZ graphics to reflect the size of the pre-cropped physical page (DIN A5) so that they will be where they need to be on the DIN A6 page once it is cropped. As the document hast 252 pages, this would be quite a lot of work, however. And I would rather not because I may also want to produce a digital version of the address book.

My Question: Is there a way to set up the crop package or my preamble such that the TikZ graphics' coordinates remain based on the DIN A6 page specification even when I am using an additional, larger physical page specification for cropping purposes?

Here is the preamble and the code of the example images (the one difference in the two images being the crop package):

Using the crop package:

Not using the crop package:

Answer 1

The TikZ overlay and remember picture options need two compile cycles to position the objects on the page. You can use this property to achieve what you want in a simple matter, this is not a perfect solution but a simple workaround:

1. Compile with the crop-package turned off until everything is stable.
2. Compile only once with the crop-package enabled. The coordinates are correct then and TikZ has not yet realized that the page format changed. The output looks as follows:

And please post a minimal working example, as not everybody has special fonts, etc. available and they distract from the main issue.

Answer 2

I ran into the same problem today. An ugly solution is to use calc TikZ library and the \hoffset&\voffset pair which is changed when you use the center option of the crop package. E.g., instead of each (current page.west), you can write ($(current page.west) + (\hoffset, \voffset)$).

My real paper size is ISO B5 and I load \usepackage[frame,a4,center]{crop}. Enabling/disabling crop together with double compilation works fine and there is no need to do the trick described by Alexander. I think that this solution does not work with some crop options like mirror or rotate.
