Print big image at many pages

[PutinHuilo]

I have 100MP image i want to print it on multiple pages e.g. 20 pages legal/A4 size, how can i split it in multiple parts? Is there plugin?

Hi @PutinHuilo

One approach is to use either Adobe Reader or Adobe Acrobat Pro and print using the Poster option for printing. You can scale the image up to the size you want and it will divide it up to fit the paper size you want to print. You can also specify if you want to have overlap in each of the pages.

If you use Adobe Reader you need to convert to PDF first before using it.
Adobe Acrobat Pro can accept many image formats directly. I supplied a cut and paste of the print window for Adobe Reader as an example below.

Hope that gives you something to consider for your project.

Thanks thebestcpu, only problem Adobe Reader it does not allow you to change landscape/portrait orientation for printed pages, i tried all options and can't make it work.

Hi @PutinHuilo
Did not know about that limitation yet you can always rotate the image in photoshop 90 degrees first and the printing in portrait in Adobe Reader should work (I think)

The thing is i already have PDF file for the camera lens test, i noticed when i import to Photoshop it messes up the smallest lines. Is there way to import pixel perfect?

Hi @PutinHuilo
Once any PDF vector element is rasterized in Photoshop you can lose some detail. There are some workarounds yet I may have an easier solution for you.
Is the supplied file the one you want to print out to many pages?
If yes, this likely can be done in Adobe Reader though I understand some of the issues.
Here are the steps I took below to get the landscape cutting to a size of 56 inches wide and 42.5 inches highe cut into 4 legal pages wide and 5 legal pages high (20 in all).
- in the print panel, set the paper size for your particular print to legal size
- turn off the checkbox "file only large papers"
- Increase the tile up (I used 450% yet the idea is to tile up until the print size shown is the size you want (in my example 56 inches wide and 42.5 inches high). As you increase of drease the tile size it will shift from landscape and portrait cuts (software "trying" to be helpful ).
- In poster mode the portrait and landscape checkboxes have no impact as far as I an tell.
- Note that the overlap amount may have an impact on the needed magnification yet I have not tried that out.

Hope that this is helpful and if not lets keep the dialog going

Right click with the slice tool then set the horiz. and vert. divisions. Save to web,

Great find, thank you.

I have printed today however even with Poster mode from adobe reader, printer still put an margin on pages (edge of paper is empty space) i checked in the shop and found no option to disable margins, now have to trim every page.

Perhaps next time i will do the print to PDF and then just print each page from PDF in regular mode, because even people in the print shop also were clueless on how to disable the border in poster mode.

I think you might have to experiment to see if you can get what you want.

Most printers have two modes
1) control of margins that have a minimum small margin
2) borderless where part of the image is printed outside the edge of the actual paper to make it borderless.

In case 1 you still have to trim all of the edges
In case 2a) With not creating any overlap, you will be missing part of the image at the boundaries
in case 2b) If you request overlap along with borderless, you won't have any cutting to do yet you will need to overlap the images
in case 3b) some printer dirvers allow controlling the amount of the image to overlap outside the print edge so if the printer if perfectly aligned, and you set this parameter then you can line up the images side by side, yet most often on one side you will have some unprinted papter and the other side lose just a bit of image.

There may be other options and just doing this from memory.

So just tradeoffs
