moving objects in different layers sideways

Asked by Caroline Kloppert on 2019-12-12

I am struggling with moving objects in different layers sideways, sizing them, and the quality of my traced objects. They impact on one another so this is about six questions in one and I apologize for that.

I have four layers with a different objects in each
the objects must align to form a four color image
the four colors are not RBG or CMYK but each layer will have a different pantone color
the objects are traces of photographs of silk screen separations
they look like fine ink drawings, with no large solid areas, just lines, or dots, and they are NOT PHOTOGRAPHS

I got it going
some objects needed expanding
it seemed easy, I would just select and then drag to get one image the right size to fit the other
for instance, I placed the black first as it is the most formative color in the design
then I placed the brown over it and dragged the brown to fit the black
This is when problems came up

problem number one
the object would expand as I dragged it, and then snap back again to some other size it seems to be choosing automatically
So I can't get the images to be quite the right size or shape by dragging

problem number two
If I did manage to get it roughly the right size, and dragged the whole object without any distortion, over the object below to make it align, it would also snap back to some point it seems to be automatically choosing, that is way out of alignment, it refuses to align using my hand dragging help in other words, it does its own thing.

problem number three
the traces made from the photographs of the designs lack a lot of the original detail.
3A
The images look bad because of this
3B
another problem is that the registration lines are lost which would be very helpful in getting the four images to sit properly aligned on top of one another
3C
I may need a more powerful camera, although my little canon does have adjustable file sizes, so I can increase the pixels
The silk screen designs or positives are large with very fine lines, A2, using a Rotring 0.5 pen
3D
but also I need to adjust the parameters of the trace in Inkscape for the best quality and I've tried many combinations without success. It does seem to depend on the size of the photograph the trace is being taken from.. I tried zooming in on an A5 arewa of the A2 design. The photograph from that produced a trace with far more detail, still not adequate but much much better.

After saving the botched up four colour image, I am unable to separate the layers again,
I would like to send you the images, but I don't see an attachment option on this forum.
It would help with understanding what kind of image it is and what kind of problem I'm talking about. so that you can recommend the right basics tutorial for me. I've been watching and googling design basics for days, and none of the things answered my questions, because the things people want to know today are different to twenty years ago when I did the designs. Even at the time they were extremely uncommonly done for screen-prints, and we ended up doing all the printing ourselves just to get it right.

I have a url where you can see the designs printed in full color

Thank you for your help

still need help with sizing and aligning the objects
but resolution problem is getting BETTER
I increased the file size on the camera to the maximum that camera is capable of, giving files of 3.2 megabites or 3456 x 4608
and when I'm doing the trace I drop the brightness cutoff threshhold to 4
I am getting much better resolution of course, because of the larger files, and I can see the registration marks even on the trace

which brings me back to the still unanswered question, aligning the objects and getting them the right size
now I can see the registration marks, four crosses, one at each corner of the design, on each different drawing
I could select a point at the intersection of these crosses
and give the command to align them in all the layers
this would cause them both to align and for the different object's size and shape to become identical
so this last thing is what I need to do

do you know which tutorial would be best for doing this ?

What about drawing the registration marks? I didn't read it all (too long), so please ignore this if it doesn't help.

Extensions > Render > Layout > Printing marks

Embedded raster images not being resizeable disproportionately - are you sure you actually want that (change their ratio)?
Or is it just that you need to disable the snapping?

Additionally, I'd suggest to update to 0.92.4, if you haven't yet, and to visit https://inkscape.org/forums for being able to share images.

Thanks for your answer

I've learned to do what I wanted with the perspective function. It is
tricky, not done one shot. I have to fiddle with the registration for hours
nudging it in and out, up and down, but I can do it now, and its taking
less and less time as I get a better feel for how to distort the images !

Inkscape's main purpose is to be a vector drawing tool. I assume that the picture from your camera is a raster graphic image. Maybe some other program (e.g. gimp) will better be able to do what you want.

Thanks, I will try that too.
