Now I'm wanting to screen print things all over the place

After drying overnight, the silkscreen paint seems very durable. I picked at it with my fingernail and it's on there good! You could clear over it, but it may not need it.

Great work!

I can make that one. Do you have dimensions for it? The screens I've been experimenting with were eyeballed and a smidge bigger (1-3/16 x 4-1/8) than the reproduction stickers (1-1/8 x 3-5/8. I want to be sure I'm doing these as correctly as I can. I'm also going to pull another screen today with a few mixes of fonts because I think what I have is too bold.

The only things that are correct on the repro are the size and colors...lol. Notice that the repop even omits the Pontiac crest above 'Pontiac Motor Divisions' in the top left margine too.

I saw your old thread on this as I was looking for emissions decals and pulled the images from it. I can make a small batch of these too.

I suspect this is how gauges were done too. I'm not sure exactly what you mean by pre-sensitized screens, but the ready made screens with pre-applied emulsion aren't fine enough for screening on metal and you'll get poor results. Most stuff out there is geared towards t-shirts which can take a coarser thread screen because it soaks in the ink. It's not difficult to stretch and treat a screen, just time consuming. So far, it takes me about a day to make a screen with in between drying time included. I've learned there is also some technique to coating a screen with just the right amount of emulsion.

Ken, That would be awesome! I need 8 for sure, but let me know how many is too much and what I owe you, or anything else you need from me.

Thanks much! Dennis

Ken, I don't need the air cleaner silk screen. I was just using it to show the imperfections of an original print. Thanks for offering though!

Have you made any emissions labels for 1969 350 HO's? I need one of those too. Thanks!

I have not been able to find any original '69 emissions label to reference. If you've got one, please send it my way.

Ken, Will do! I hope I find an accurate one.

Just for reference, here's Dan's '69 350HO Firebird's original air cleaner (PV code 6485501) with the HD filter option.

By pre-sensitized I meant light-sensitive. Basically, you buy a screen that is pre-coated with a photosensitive emulsion, correct? This vs coating the screen itself, then "sensitizing" to activate the photo-chemistry.

And I can appreciate the effect of mesh size. Some of my wonder years were spent in a lab making prototype microelectronics. We screen-printed "hybrid" circuits so I've got some of that in my two remaining youthful memory cells. We also did a lot with liquid and dry-film resists. It was interesting, just like what you are sharing!

Here's the last time I thought about the gauge graphics. I have a dash tach I may play with if I run out of elder interests... your success might motivate me!

Ah, yeah - we're talking about the same thing. I tried a few pre-coated screens but the mesh wasn't right. It's more labor intensive, but so far coating my own screens seems to work best. My entire experience with silkscreening was a few week in Industrial Arts class in High School.

Yeah - gauges are an interesting one! I was looking into dry transfers as a solution for these too. Expensive!

Speaking of, I put in for an order of waterslides for '67 and '68 coolant decals, '68 standard and Ram Air emissions, and '64-'65 fan guard decals. At this rate, I should probably invest in my own ALPS printer.

I put together a sample panel to try out a few different font assemblies and finalize sizing. #1 is what I put on my air cleaner in my test the other day, but the fonts looked a little too bold.

After some closer inspection of pics of originals, I think #4 and #5 are the most accurate but would love to hear from folks. I did this in one pull across the screen, but I'm finding the fine mesh is pretty forgiving and I could have done a couple passes to thicken up the print, especially if you want to replicate the sloppiness of the factory application.
