Help! Newbie, size/printing issue....

Postby Terrilin » Fri Dec 20, 2013 8:34 am

Hi everyone!
I am using inkscape to "digitize" my sewing patterns, while also utilizing the program to clean up my hand drawn lines from the sewing patterns I scan in.
I have learned the technique from this video https://www.youtube.com/watch?v=6PxutMjCFOg and it helped me figure figure out everything I needed at the moment.

My issue is, when I go to print the pattern it is smaller than my original scanned image and it has to be the same size. I have printed my scanned image after I've put it in the computer and it comes out the same size as the original. When I put it in inkscape it gets smaller or something???? I have no idea!
I am not re sizing anything while in inkscape (maybe I should be?)
I apologize for my newbiness! This is the last piece of my puzzle and I cannot figure it out!

Thank you all for looking
Terri

Hi Terri!

That video creates a raster based pdf of your linework image, which is not a good solution.
The quality will get some loss at least by jpeg comression, while the file size will be bigger then if all kept as a vector file.
The different size problem is because of all of this unnecessary rasterisation.

How to do it the other way?
Open the document properties tab (Shift+Ctrl+D), and set base units to be mm -or inch.
Draw rectangles in the same size you want to print the pattern -preferably use a vivid colour, about 50% transparency and no outlies (Shift+Ctrl+F).
Then place them into position for a print layout -use the align and distribute panel if you like (Shift+Ctrl+A).
Maybe keep in mind the print margins too, and place rectangles to intersect each a bit.
Hmm in that case, you better add somekind of a grid to the design too, so that you can stich the pages together after the printing is done.
Save this as an svg.

Now, as inkscape itself cannot save pdf-s with more pages, you would need to save each page with the part of the design to separate pdf-s, then use another program like pdfmerge to put them all together.

So.
Select the rectangle of the part you want to print,
resize page to selection in the document's properties panel.
Select the pattern you want to print and the paper sized rectangle above, and set clipping.
Then select inverse (!), and delete those.
Then save the result as a pdf, with the area set to be the page.

Then open the previous svg, and do the exact same things.
Repeat until you have all pages as a pdf.
Then run pdfmerge, and there you have it.

Good luck!

Thank you Lazur!

I forgot to mention that I actually stopped at the Gimp stage of the process and have not formatted them into pdf. But I am also wondering if dpi make a difference. I noticed last night that I was scanning the prints in at 75dpi and inkscape was at 90dpi. I set both my scan and inkscape at 100dpi last night but have not done the process again to see if it worked.....
I will also try it the way you have suggested.

Dpi does matter with raster images.
Usually text doesn't come out nicely under 300 dpi, and photos under 600 dpi.
If you somehow could print your raster images at their true 75 or 100 dpi resolution, they would look pixelated.
