I just test printed decal paper using a solid ink printer and it looks really good.
Yellow paper black ink.
Size test - I was able to print up 3 and 4 point text with no problem. I even printer .5 mm text. It was a little blurry but still legible.
Stress test - I printed on the same sheet 3 times to induce failure so I could see what the deteriorating effects would look like. I started to see the ink flake on the third pass. It looks like the heat from the printer causes the decal sheets color layer to repel the ink. I'm guessing that the heat cures the decal layer. It should not be a problem because it is only suppost to be ran one time anyway.
Bonding test - The ink bonds pretty good but will rub off if you apply enough pressure (heat/friction) and just like any decal it can be scraped off. I folded the decal along the text and the ink still adheres to the decal color layer.
Over all it works. The last issue compared to ALPS is white ink. In my test I uses the revers blocking of text to verify the density of the inking when blocked and saw no problems.
Why the blocking test? The printers ability to manage pantone colors allows you to color match. With this you can use white decal paper with reverse blocking and blend the decal into position.
As soon as I get my TTX and BSNF fonts squared away I''ll make a run.

ALP alternative - Solid Ink
Re:ALP alternative - Solid Ink
OK, what is solid ink printer. And are you saying we still can't do white. The reverse color method will not work in all situations. I need white decals. The benefit of the ALPS is still the white.
Does anyone know why no company supplies a white ink? Do we have the resources within our membership to create white ink ourselves to load into empty cartridges, say my black cartridge for my HP?
Re:ALP alternative - Solid Ink
The ALP is far and few between even. On e-bay the problem is not knowing the condition and how long it will last complicates things too. From what I see the N-scale products are getting better in detail and our requirement for precision decaling will increase also.
I will test the color matchin abilities in the later on this or next week so we will see how will the matching will work.
The pantone printing has 36 shades per block and is adjustable. I think the only limitation could be metalic coloring, but those are grays anyway.
I printed a color chart and I will see it I can match the CFX blue.
The ALP does have the advantage of the white but I have found that the when you use new decals they are too white anyway. It seems things are tinted more so gray/white or yellow/white and weathering eliminate the need for pure white also. I started this search because I wanted a perfect match on my re-numbering of my well cars. I still trying even tho Rich show me didnot have to worry about the matching :lol: .
The translucent effects of white ink makes it difficult. White ink on red shows pink and one would have to reprint over and over to color out the effect of a red base.
The ALP stamps the color onto the paper verses being painted on like ink jets, but my problems with the ALPS is not only the availibity but the quality. The max for the ALPS is 1200 dpi. The new solids are hitting 2400 dpi. I printed .5 mm and it was legible. That's pretty good for desk top printing.
The solid ink printersuses these ink blocks (like crayons) and it melts it on the paper.
I'll post a pic later on tonight showing what I've found and what it looks like.

The yellow decal is from my abuse test. You can see where I rough it up a bit. It can hande normal usage.

Re:ALP alternative - Solid Ink
I had trouble finding the right fonts used by TTX but finally found something. I still have to make a few size adjustments before I start the final printing.
As for the color matching I will be trying to match the off black color of a Cancarb tank. It looked ok on the plain paper but the real test lies on the trim paper.
The found a issue when trying to laminate a solid ink print. The heat from the laminator causes the ink to bleed a little or changed the color of the ink. SO this is something to watch for it you laminate a lot.
Getting sleepy so I will update you tomorrow after I start the decaling again.

Re:ALP alternative - Solid Ink
Sized the fonts up pretty close and printed the first sheet and learned something right away.
Pixelation!
The printer uses different color dots to make up the colors spectrum. Deep colors are fine. The problem starts when you get into the shades of colors that uses white.
I colored matched the black on the Cancarb tank using the regular white paper and it looked great. The problem is the decal paper is an off white so the pixilation effect changed the color tone. The white areas registered by the eye on the regular paper were a really close match but the white used on the decal sheet changes everything.
The remedy is to create the color chart on the same type/color of paper used in the final printing. This allows for the principle WYSIWYG
I'm sure the real printing and graphic people know this already :lol:
I printed the second sheet with the text just pure white (which is considered transparent to the printer and allows the decal paper to represent the color white) and the text came out clearer. (There was no problem with the decal paper tearing or any material flaking off.)
Looking at the white ink issues again, I think it can be resolved by making color adjustments on the printer so colors can be dialed in. It may take some time but I think it can be done.
The decerning factor will be how white the decal sheet is.
Conclusion
There was a brand new ALPS on ebay for $1000! I though that there has to be new technology out there and for that price.
The fact that the ALP is out of production and somewhat of a speciality product now, takes away from a lot of its +'s.
The white ink issues still has that draw but I think the over all quality and functionality of the solid ink printer pull me back across the line.
Over all I think this is a viable solution for decal printing.
I printed a .08 inch stop sign legible and text legible at .02 in so it can handle the small jobs.
I had access to a 8560 and did all my testing on it.
I saw Costco had the 8550 for sale for online with a $400 rebate putting it @ $499 it does (2400x600 dpi) which makes it a little better on the pocket.
I'll post the finished products later on today or tomorrow.

Major set back
Thanks for the info Greasemonkey
I started to apply the decal from the white sheets and noticed some flaking issues. I did the scratch test and boy was it bad. It came off like toner on glass, well not that bad but bad enough.
I started to freak out? Thinking all this work for nothing! So I started to test Microscale and Testor with the same results. Going over the other test cases I made, yellow and red sheets passed the scratch test with no problems.
Going back to my desk I'm thinking the golden rules of test and evaluation.
Never assume and test all cases thoughly and equally. Looking over the results of the white and clear sheets I came to the conclusing that the yellow and red sheets are laser decals and the clear and white sheets are inkjet. The inkjet requires a protective clear coat. Which is like paint so the decal sheets are different. I have to make sure that I use the laser type decal sheet not the inkjet :oops:. Although this entry seems calm and collective the truth was, I was running around like Chicken Licken until the laser paper theory klunked me on the head.
Now, I have to locate the laser type decal sheets.
Why can't my projects be 1,2,3 finished

Re:ALP alternative - Solid Ink
Just ran the laser paper and it came out better. I also tested another yellow sheet and it doesnt seem to hold up as good as the first sheet. I'm not sure if running the sheet through twice made it hold better, but there is a difference in the ink jet vs laser paper.
I have all the decal printed using the reverse white blocking and will start applying it in a day of so. I have to clean up this mess first and maybe enjoy the last few hours of this weekend.
I made new road number for
TTX well cars
TTX Auto rack
Cancarb tanker
Rail box
WP center beam
As soon as I complete the installation I'll come back and try to sum the
solid ink printer from a newbie's prospective.

Re:ALP alternative - Solid Ink
OK, here's the lastest.
I'm some what dissappointed in the results.
The on going issues with the flaking are still here.
Here is a image that would represent the naked eye.
This is a 3X close up
Notice the white edges and the flaking.
This is the effects of shrinkage. The numbers were cut extremely small. It appeared that the white layer shrunk after being dipped in water causing the edges to seperate from the solid ink. This exposed the white layer and caused the framing.
To address the shrinking issues I started cutting a larger border to dispurse the shrinking over a wider area making the final cuts without the paper backing. This helped out a little but the potential for the separation is still there.
I tried to remedy that by using the Microscale liquid thin layer film but that caused a chemical reaction to the solid ink. It started to slightly desolve the ink but it only address the surface bonding bot the bonding between the ink and white layer.
Reflecting on the initial bonding test, I recalled the ink having bonded to the yellow paper good. So I went back to that test case. I realized that running the paper through a number of times made the ink adhere to the paper better.
Reasoning that the only bonding catylist on the printer was heat. I preated the oven. Places the decal sheet in the oven. I came back to find the paper well done :oops: .
Let try again! This time I places it in a few seconds but the metal rack burnt stripes on the sheet. The sheet blistered in some places . I did noticed a stronger bond in the areas between the rack marks.
Now, I will test heating the decal to get a better bond (blow dryer).
ALPS anyone?
No no, keep focus. ALPs is out of production.
