When printed, the RGB color that came from CMYK will be converted back to the same original CMYK color
Nop... It will not.
There are several reasons. Color profiles, changes in gamut, simulations on the screen...
But I will only address 1.
A CMYK value has 4 variables (C+M+Y+K). A given color can actually be created using a combination of inks, mainly ...
You are not attacking the core issue of the problem.
It is perfectly fine to design printable material in RGB as long as you are cognizant of the fact that certain very vibrant colors wont come out as vibrant as you think and as a results crew up the entire palette. Just dont choose the most vibrant colors.
However, this is not a huge issue, you can learn ...
Inkscape has several options to "select all same". Select one circle and try for ex. Edit > Select same > Fill color and press DEL. Before pressing DEL deselect all unwantedly selected grey parts. Click them holding Shift at the same time. You can also lock other same colored shapes in the Objects panel.
This is a guess: fl is a ligature, a special character which contains f and l together.Many fonts have them. I do not try to guess the exact method how you did pick it.
Here's a part of Arial's special characters, in the beginning of the list there's fi and fl
Advanced typesetting software can place ligatures automatically for nice looks instead of ...
Maybe this might not be the way to draw in a vector graphic program, but it can be done in a few steps:
duplicate the lower polygon. The additional shape in shown in red
select one copy of the lower polygon and the upper polygon and create the division between both shapes:
Now select the other copy of the lower polygon. The part within the ribbon can now ...
I would use a slight lighter to darker red vertical gradient on the button shape by sampling the colours from the example graphic, then overlay with some blurred black rectangles with reduced opacity at the edges.
Group everything, then copy and paste the button shape in place, then apply it as a clipping path on the whole group.
And here's ...
The masked out squares are still the same colour, just hidden behind the mask. That's why Select Same is selecting them.
Instead, use the Edit Paths by Nodes Tool (F2) to select them by clicking and dragging a selection only around the squares you want to select, or select them manually by clicking on each one while holding down Shift
Switch back to the ...
Inkscape isn't the right tool for your attempt to reproduce that image. It's not theoretically impossible, but Inkscape hasn't easy to use deformation tools for creating the wanted apparent 3D form.
In Inkscape you can make a straight plane image which contain that hexagon based structure. Without knowing the exact wanted structure I cannot write anything ...
Option 1: Use the 'Pattern along Path' LPE (or the corresponding extension - description is for LPE)
Make your design (a dash and a number, or maybe a second dash, too)
convert those to a path (you might need 'stroke to path' for the dash), and combine them to a single path
copy that to clipboard
select the rectangle
apply the LPE to it: Path > Path effects ...
There's an extension for making a pattern for an actual lace (not only a drawing of one), maybe it could be useful to you: https://tesselace.com/2017/10/31/inkscape-for-bobbin-lace/
If it's circular, the 'rotate copies' live path effect is an option, too.
I'm using Inkscape 0.92 on a Windows 10 PC. In the Text and Font dialog (Shift+Ctrl+T), just beneath the Font size drop-down there is another drop-down with a percentage value in it. If you put the cursor over it a hint label appears telling you that it is for Text path offset - it does the same job as editing the XML (as predicted by Scribblemacher). The ...
It's much more complicated than you think because CMYK is not CMYK and RGB is not RGB. But luckily, it most likely also isn't a problem. Be sure you have the correct color profile for your monitor so the colors that you see are actually the ones you expect (well, mostly... as good as you can get them), and you're almost certainly "good to go".
In respect to ...
How about using the spray tool for this?
It has options to
prevent overlaps, with distance setting
only spray on areas that are not transparent (i.e. on existing letters on an empty background)
Are the boxes of equal size, color, stroke width and orientation? So for example you would represent the upper, horizontal line of the E with 7 boxes in width, 3 in height, each with equal spacing?
You might either do it by cloning 2, 3 sample squares, positioning them and then look at the XML and generate all the square clones with a short script.
Just copy/paste "⬤⬤⬤⬤⬤⬤⬤⬤⬤⬤⬤" as text, select it and your circle (which should be a path), and use Text > Put on Path.
Boom! No complicated steps, no changing your circle, no distorted dots (which is what "Pattern along Path" gives you, especially when you have large dots).
Plus it works well no matter the shape you're putting the dots on.
