Part 1: Learning how to trace
Differences between the raster process and the vectoring process
When rastering, you don't want it to go all the way through but you do want to make sure it has a clear outline so you do want to make sure you raster it as powerfully as you can without doing any damage to it. You also have a new option in the settings, which is DPI and that stands for dots per inch and means how accurate it is to the original drawing, more dots per inch means more accuracy but also more time spent, just like a 3d printer when you decrease the layer height.
(above) the kfc logo after I traced the bitmap, you can see the before picture on the left, the traced picture in the middle, and the outline of the trace on the right. I choose the kfc logo since it has alot of small details that would be good to practice with
The two images on the right are my bitmap version of the kfc logo and then the version of it after I traced it. it is hard to notice but the bottom was is generally less pixelated
Part 2: Using that in the real world
on the right you can see my cardboard cutout on the sheet. the cutout was a bit too low and therefore I failed but it didn't hit any other boxes so I'm counting it as a success.
and on the right here you can see a comparison between the cardboard leather keychain and the leather one. the cardboard cutout I did looked identical to the leather keychain that was premade and I am really proud of that, and I also slightly increased the size of the engraving lines on the leather than the cardboard which made it also come out well
Differences between digital and physical design and what rasterizing is and its differences from vectoring.
on the digital design the lines look much less straight and thinner than that on the physical, as you can see comparing to two images on the right. rasterizing is like a low power cut where instead of going through it just marks the outside to make it visible where you engraved at.
The only problem I encountered while doing this was the sheer fear in me as I was the first one to cut on the cardboard sheet, I eventually just got over it by clicking print and being ready to stop it if it cut in the wrong spot.
on the left is my finished keychain with the metal band attached
and on the left down here is the keychains design, I used trace bitmap twice, once for the shape of the leather and another for the decal, which is a ultimate frisbee in air
My teacher decided that since I was ahead I should watch the 30 minute cardboard engraving for the cardboard sheet shown above
