EEVblog Negative Feedback Shirt quality
« on: February 27, 2014, 08:46:40 pm »
Hey dave!

I was thinking of getting one of the awesome negative feedback shirts.
If you look at the preview on the teespring website though, the stencil looks like it's pretty poorly cut out: http://images.teespring.com/uploads/2014/02/23/08/406080/shirtFrontBig.jpg

Specifically the black bits around the opamp schematic... It looks like it was cut out from a black background without any feathering.

Is this just on the previews, or does it show through on the actual shirt? You can sort of see it on the shirt preview as well

that's interesting.  hope the real shirt does not look like that.

its probably worth checking before a bunch of people get them.

I knew the text looked like that, but I didn't notice the black bits around the circuit. No idea how it will come out on the shirt I'm afraid.

any way to ask the shirt company for a 'proof copy', before they run off 100 of these??

Here is the original uploaded file.
I didn't see the black around the circuit because I had a black background set on my image viewer.

if you look at the image 1:1 (pixel-wise) there are lots of issues.

is it too late to update the graphic and 'stop the presses' until a cleaner one is released?

hope that's not being too fussy; but if it was my graphic that 100 people were wearing, I'd be a bit of a perfectionist and would only want vector art or clean raster art for the submission.

Too late for automatic update, yes. But they can probably do it manually if I send them a new graphic. If someone has the skills to clean it up, please do so.
I kinda liked the distressed spotty nature of the text, but I agree that the circuit has to be clean at the very least.

I tried quickly to clean edges and make fillings more solid. Now edges are not so perfect and bit coarse, but can't do better, whole image would need to be converted to vectors, and that takes some time...

Thanks but it needs to be a transparent PNG for upload to Teespring. Supports .EPS too.

Circuit looks good, but I see nothing on the text Irfanview. It's white  instead of the gray colour?

Neither Irfanview or GIMP can read that.

Removed artifacts.  Looks like it was originally a gif or antialiasing was on.

I also gave it a shot (used the ancient 'xv' program under linux).  used the color editor and tried to combine the colors and reduce the color count.  that often helps, but in this case, there were still 'dot-lets' left behind and it would need manual cleanup.

sheesh.  just do the thing right for next time ;)  do the schematic in vector and do the lettering in a real font so that its vector, too.

liquibyte's version looks quite good.

Ketturi's version does not have the rounded edges, that I think dave was shooting for.

 you guys do fast work, lol.

the spotty nature looks like a bad printing job.  or a bad drawing job; not an intentional 'effect'.  if you have a cheap tee and some of the screening comes off in the wash, it would look like this.  not sure that's a good thing, to be honest.

Hmm can't seem to get this working with Irfanview. If I lave at 256 colours it doesn't save the transparency properly. If I reduce to 16 colour I get the outline around the circuit and text again...

My attempt at it

One EPS (zipped) and one PNG both with no background (text is white so it may be hard to read)

D'oh I used wrong file, my bad, and l liquibyte did great work too.
I'd say we go with it. (I won't make another try as I'm going just now to sleep fever&flu off...)

liquibyte's version looks quite good.

I think it looks wrong somehow, like the characters have been eaten away. Plus the ground symbol and +/- are missing!

if its a raster file, I prefer to save as tiff format.  I trust tiff not to muck things up and that does support 16bit color.

yeah, stuff did disappear from that one.  didn't notice until you just said so.

maybe some parts went away because they were done in slightly different rgb values?  there were a few different shades and I tried combining some, while mapping others to pure black, in a version I was working on.  it still needed work after that and I saw others were working on this and had better results, so I gave up on mine.

Ok, one last try  :P
Now it has only 2 indexed colors + alpha, if that won't work, something is wrong either with Daves irfanview or gimp on mac I'm using...

Regardless of who's version I use, saving as a transparent files in Irfanview causes outlines around the text and circuit.

If you install inkscape (free) you can open any of the original files. Click Path > Trace bitmap up in the top menu and make sure you select "Colors" is multiple scans. Then you can select what ever colours and scale to any sizes you want. Then export it to the file type you need.

Ketturi has finally nailed it!
Here is the final version, I fixed the size to match the original, and it's transparent.
No artifacts present with either white or black background when viewing.
Thanks!

In attached file you can find the following formats (background is transparent).
.AI (Adobe Illustrator)
.SVG
.EPS
.PNG (200DPI)
.PNG (300DPI)
Original picture was vectorialized with VectorMagic, black background was removed, white letters were changed to the same color in your original picture.

Ah, that's even better, thanks.
But I've already emailed the other one away, so will use this next time and for future variants. Now I have a good base to work from.
