Photoshop :: Cleaning Up Scanned Line Drawings
Jul 15, 2005
how to get them clean and crisp? black ink drawings is what im scannin in, ive figured this much out; scan it in at a high resolution (i scaned in at 600dpi), scan it in grayscale, mess with the levels. the overall goal is to scan in a line drawing and color it.
im trying to get the lines to be a uniform solid black. ionno if this is something i should try to get when im actually drawing it or something that is best left to PS. it looks pretty good on paper but when i got it in PS the lines are not as solid as i thought.

I am a newbie to Illustrator. I have scanned in a drawing and opened in illustrator. As it was a jpeg, I then image traced it to turn into vectors - it looks very messy, is there a better way?
I now want to colour parts of it in, but it only allows me to use black, white or gradients in between, how do I add colour? The document colour mode is RGB.

I often scan b/w documents with my scanner to Photoshop. The scan always has spots (noise) which are time consuming to remove. I'm basically zooming in and erasing each one.
Does anyone know of any easy time saving steps/procedures I could use to remove these spots?

my girlfriend's birthday is coming up, and I wanted to do something a little bit different. She's a great artist, and she's drawn a lot of pictures of us together. She's so busy though, that she never has time to finish the drawing completely, so she can't get around to coloring it. I was wondering if you guys could point in the right direction of how to color scanned black and white drawings?

When I used to use photoshop a long time ago (version 5) there was a technique I used to use to draw over the lines of a picture so that I could colour it how I wished and use the shading and burning tools etc to add more life to a picture. However I no longer know how to do this and I'm on version 7.
Basically it involved the lines tool, I would draw around each line of the picture, then add the end use a tool which made the lines smoother and more curved so it didnt look like it was drawn with a ruler, then it would be easy to select the areas in between each line and colour.
When I try to do this in 7 it creates a layer for each seperate line, and I dont remember whether it used to do this or not. Also I cant for the life of me find a way to smoothen them all out and make them as one whole layer like before, instead im left with many awful lines which overlap etc.
how I can do this effect, or a better way of doing so. I read one tutorial that said go over the lines with the pen tool, but that doesnt work at all, and going over with the brush doesnt leave nice defined lines at all and makes it hard to select the blank areas.
I'm using scanned colour drawings of mine.

I have several hundred TIF images at 1200 dpi+ which represent scans of hand drawings on parchment paper using pencil or ink-pen (.2mm or thereabouts) of 4000 year old cuneiform documents. The drawings were made over an extended period of time, the paper varied, and ultimately, the scans reflect this in that some lines are darker than others and there are occasional 'smudgy' areas etc.
What I would like to do prior to publication is to sharpen the images and make them consistent across the repertoire as black on white background.
how various Photoshop (CS5, Mac) commands do what they do, but I've found several that seem like they might get me where I want to go: Levels (Auto?), Threshold, Shadows/Highlights. I'd like to automate to run over a directory of images if possible. At the same time, I might have to change the dpi and output format of the new images.
In this case, the drawing is fairly clear (not much 'grey' background) but the lines are not as black and sharp as they could be.

I love to draw, I would like to use my drawings on some iPhone game. I am wondering how I can process the drawings I scanned into a high definition image? I do my drawings in old fashion paper and pencil way, once The drawings were scanned, the resulting images look very rough, for example, the lines are showing the pencil marks, a straight line has a few bumps in the middle, and circles seem a bit off, is there a way in Gimp to do some fine tuning on the images?

Any ideas how to convert photos to line drawings? The best I've come up with so far is greyscale, then filter / stylize / find edges. Not bad .... but I think I could do better.

What controls the line weight in idw drawings in Inventor 13? If I zoom in on a section the line gets wider as I zoom in until it looks like a pdf drawing. I don't have this issue with Inventor 12.

I have a little issue with drawings where I cannot find out how to highlight fillet edges on the models. I dare say I am missing some simple setup option.
The picture attached shows what I mean. The left is how the model looks in drawing mode and on the right is how I would like it to look (taken from the modelling environment).

It's possible to select a part in a view on a 2D drawing and change the color of all the lines belonging to that part.
This is really useful, but is there a way of assigning a line color to the .ipt file it's self, so that every time I place a view of that part the lines are automatically set to specified color?
This would also be useful within a single drawing when there are multiple views of the same assembly. e.g.
Part A would always be drawn in Red, Part B would always be green. This would really distinguishing between parts in complex assemblies. (Which I realise can be done manually but I think it could be done faster with less chance of making mistakes.) Currently, I color all the parts, but then if I make an additional view, the new view is all in black.

I have an iassembly model with iparts in it. I am trying to make one absolutely complete model rather than have several models with redundant parts in it. For example having the full assembly and making a Top Line Drawing from that, but then also making a drawing from the individual components.
So for example I have a Top Line assembly drawing with a tank with all the fittings, gauges, and instrument panels shown. Then I would want to make another set of drawings showing the tank itself, fittings, gauges, and the instrument panel. My main issue is with the tank drawing; the tank drawing is supposed to be simply the tank so I would need to remove the fittings, gauges, instrument panel etc.
I would like to know if there is a way to "Hide" or "Supress" the components that I do not need for a particular drawing without taking them out of the model; yet at the same time removing it from the BOM because they wont be necessary at this level.

Question 1. How would I make a cartoon drawing/picture or a drawing/picture with color, Into a drawing with lines only, no color. I use the gray scale option and that works great, but it still has the shading of the drawing/picture, and I want lines only. So is there some what of a easy way to do this?
Question 2. Once having a line drawing if some of the lines are a little shaky or kinda looking to pixel ish, Is there a simple way to smooth these lines out?

In drawings there are a lot of times where I turn off the visibility of certain line segments to make the view look cleaner.
What if I was to reverse the visibility of these lines segments down the road?

In the attached screencast video you will see that I have a drawing set up on the left of the screen to show where all the sections are taken through the building. I have setup a layer called SPC SECTION LINES which is set up to be bylayer and on the colour green.
When I XREF this drawing into the sheet file on the right side of the screencast you will see how the colour turns yellow when reference into the new sheet file?
Why does the colour of the line change when it gets xrefed into a new drawing?
the screen cast can be found at [URL]

We've having an office wide problem of drawings getting bogged down with, in some cases, hundreds of linetypes. Not sure where the source of the problem is coming from but as we contiunally use the drawings they keep gaining more and more linetypes, like a snowball rolling down a hill, and the files become so large they are almost unusable. The linetypes don't purge out of the drawing and are not connected to anything. I've tried everything I can think of to clear out the linetypes and the only thing that seems to work is wblocking them. Which when we're talking about hundreds of projects consisting of hundreds of files is a lot of work. We do wblock the drawings in a project on occasion to keep the files usable but they just become infected again eventually.
What might work to clean them up on a batch basis? I've attached a file that's infected so you can take a look. This is a file that has never had anything xref'd into it and was created as a brand new file when originally created. At some point over the last 3 weeks it got infected with the linetype disease.

The 2D drawings I am working with were exported from 3D REVIT files to 2D AutoCAD files. There are several XREFed drawings that are both mechanical and architectural from the original REVIT files that for whatever reason, the block's line weights came over with line weights of 70 in those blocks.
When I plot, the objects are a blur with the line weight so high. I tried using the command "setbylayer" but that didn't work since nested blocks still had lineweights of 70. Is there a VBA or LISP routine to run through all the blocks (including nested) that can change the line weights to a given number?

I have a pretty high resolution map of Manhattan in 1884 (screenshot below). The bones are good and it's what I need for a research project, but I'm finding it next to impossible to clean it up to the point where I can start. Ideally I want to get rid of everything but the gridwork of the streets. I can desaturate it and play with curves and levels, etc., but while I can clean up a lot of it, I'm finding it pretty much impossible to isolate the street grid. I already have 500+ text layers for street and avenue names. I'm hoping there's some way to do this that doesn't involve me setting up a new layer and tracing the whole island, block for block.
I'm using CS6 on a mac.
I'm fairly comfortable with photoshop; I can work with layers and masks, etc., but this is beyond my technical skills. I'm wondering:
1. Is this doable at all?
2. Am I missing something obvious?
3. Should I start over again with Illustrator?
I'm not very familiar with Illustrator, which is why I started with Photoshop. However, this is not anywhere near my area of expertise

Have some questions regarding follow up on my installation of PS CS6. First thing to say is that I hardly ever use PS. I use LR4.4 99.9% of the time, but occasionally have gone to CS3 for small adjustments even though I don't really know how to use it. Planning to learn now that I have 6. I'm running 10.6.8. (Disappointed that I can't upgrade to LR5 so will, at least, need to learn content aware, which was my main reason to go to PS6 anyway.)
So, the questions:
1. I have CS6 standard upgraded from CS3 extended. Any reason to keep CS3 around for low-level, general photography editing to take advantage of its "extended" qualities?
2. Other Adobe software that seems to have tagged along with other Adobe programs:
a} Adobe Stock Photos CS3? Nothing even opens when I click on it - can it go?
b) Device central CS3 - assuming it can go if CS3 goes but I don't see a "Device central" for CS6. Don't really know what it is, anyway.
c) Extension Manager CS4, CS5.5, and CS6. Can't imagine where the CS4 came from. CS5.5 probably came along with In Design 5.5, which is still in use, so probably keep that? Assume keep CS6.
d) Bridge 5.1 and 6. Looks like they are both picking up the same things. I don't use it since I'm using LR. Figuring get rid of 5.1 and keep 6 just because.
e} Interestingly, no ACR came tagging along with PS CS6. Since anything I would send to PS is going to go through LR4 I don't see a real reason to have it. I think the new fun stuff on LR5 isn't going into the new ACR anyway and, I figure I wouldn't be able to run it on 10.6, it doesn't seem like I really need it.

I have an old photo of my brother and his surfboard that is very grainy and dark. It was taken with a very old camera and has been abused and cracked through the years. I have scanned this photo and would like to remove the grain. I don't really care about the background, but I would like my brother and his surfboard to look sharp and clean. I tried burring the image to lose some of the grain, but I then lose alot of the contrasting lines and obviously the sharpness of the image.

I recently received this poor-quality Xeroxed scan (below) as a PDF, and was asked if I could enhance it to show the names written on the pages. Does anybody know of a way to improve the quality of this image so the names are more legible (original image size is 8x11)? The image is of a logbook of prisoners interned at Buchenwald concentration camp in 1944; my friend's father's name is on the left page, about halfway down. The quality is actually much better in PS than what is displayed here. If need be, I can email you the original PDF, if that'll help.

I have some jpegs (72 dpi) of family that I wanted to print out and put in a collage for a family reunion. I would like to enlarge them, but of course this makes the pictures pixelated and bad quality. Is there a way to get around this and make them look better? I could swear I have seen a plug-in that does this (or simulates) and helps make pictures look better with more detail. If there is any special tips or tricks or even recommendations of plug-ins on how I can achieve this,

My client requested that a lot of the visual clutter in the sky be removed - I agreed and was happy to oblige. My skills in Photoshop are modest, so it took me a very long time to finish the job using an assortment of the usual tools.
I suspect there are faster and easier ways to accomplish what I did.BEFORE:[URL]...
