  1. Need Help Acrylic - Flame Polished - Craze

    I'm no scientist, but I did stay at a Holiday Inn Express last night. YouTube rabbit-hole has plenty of videos regarding this, and attached comments are sometimes useful in explaining what's going on: Flame polishing basically melting the surface of the plastic. When flame is removed it...
  2. Halo-letters using .080 faces and .063 returns? Sources?

    wicked. we go .090" minimum for halo letter faces, but usually .125", as with thinner metals you can get "hot spots" where you weld the returns.
  3. I really need a tip or trick about now to get rid of this issue? Before i go crazy :)

    static as a cause, most of the time I've seen, is an over-used diagnosis for "i don't know". I debunk it often, as it would not be isolated in just 1-2 channels. you would see issues across all colors. Also, if it were the case, you would see fuzziness/overspray/ghosting within your white...
  4. Help Attaching An Acrylic Sign To A Hollow Core Door.

    visible mounting hardware? hollow door anchors, with instructions on how to drill holes into acrylic without cracking invisible mounting hardware? hollow door anchor + acrylic block, 2-4 of them, depending on size. install blocks, mount sign to blocks with vhb tape. naysayers, chill please...
  5. Sp-300v - Color Shift After Head Soak ???

    what was reason for the soak? missing nozzles in a print WILL shift the color, as will regaining nozzles from a cleaning. royal blue is made is cyan and magenta, green is made from yellow and cyan. if you're getting greenish blue, then you've either got yellow ink contamination somewhere, or...
  6. Mimaki jv3 sp 160 wont startup.

    those ribbon cables have grooves in them that are perfect channels to direct ink down to the connections in the printhead. any time you remove the dampers from the printhead, you run the risk of dripping ink into electrical components. you may have cleaned the cable, but the connections may have...
  7. Internet Browser

    the only purpose for internet explorer, is to download & install google chrome. firefox used to be my go-to, but they sold out to yahoo and now anything you do via firefox redirects through yahoo search engines...even if you designate google has your homepage and default search engine, it will...
  8. Ul Standard

    same goes for getting engineering stamps of approval. if you follow UL spec/certification, you may actually save most of that $$$ on your liability insurance.. ...the rest you make on being the sign guy that can actually do the work in your area. besides, what's the price-point for freedom...
  9. Vinyl For Hdpe

    Top ones, that I know of, are 3M IJ39-20(cal), Arlon DPF8000(cal), & Orajet 3105HT(cal)/3951HT(cast) however, it is ideal for surface to be completely smooth & CRITICAL that the area to be applied be blowtorch'd gently to modify the oily-surface to better accept the adhesive.
  10. Need Help Jv3-160sp Head Issue

    Definitely looks like an ink flow issue. The ink system operates like a siphon, who's flow is refreshed by the ink pump when the printheads park on the capping station. Black shares an ink pump with an adjacent color, i think magenta. So you can most likely rule that out, if the magenta is...
  11. Question Reverting Back To Original Mimaki Ink ?

    chemically these inks are nearly identical, else they wouldn't work in the printer in the first place. its not like one brand uses ammonia and the other uses bleach, in their mixes. i'd chalk it up as a "sure why not", but for ease-of-ordering it's much more simple to stick with a...
  12. Peeling Liner Off Vhb Tape

    manageable headache when peeling longer strips, but when you need to peel dozens&dozens of <1" tabs for detailed lettering I will take a piece of vinyl backing & apply a long strip of VHB tape, remove the VHB backing, and cut & apply tabs of "pre-peeled" vhb to letters as I install. also, +1 to...
  13. A Bit Of A Pickle...

    +1 routine maintenance & profiling, and your prints should come out the same everytime. I'd bet money that between first running the job and then reprinting you had some clogged/un-clogged nozzles in your printhead along the way. even a 1% difference in nozzle test prints could yield a visible...
  14. 3165ra Failing

    nope, more than one piece of literature, from various suppliers, recommends NOT using 3165 for vehicle graphics or wraps. most likely result of known issues in the past. anything exposed to the elements, especially those not on a perfectly flat surface, we use cast/highperformance materials...
  15. Cornhole Boards

    I laminate all the graphics I coat with poly, corn hole boards included. seems like a lot of work just to skip lamination & chance smearing your graphic and/or causing the product to fail entirely.
  16. Hp L26500 - Reinstall Printhead Errors Keep Happening.

    that sucks. everytime i've gotten that message on my 26500, i've just removed & reseated the printhead. One time I got the error again immediately after, and simply pressed hard on the ink-input-side of the printhead, without reinstalling, and it worked like a charm! shootin' from the hip...
  17. my jv3 is not pulling ink to heads

    access the drain lines above your ink pumps, from the back of the machine, and draw ink with a syringe (SLOWLY!!!) while the printheads are parked on the capping station. also, while you're back there, swap the lines between the "working" colors and "non-working" ones, and run a fillupink, to...
  18. Oracal Issues

    ultra/high-performance calendared, is still calendared. calendared is produced like taffy, mushed around & stretched to shape, and it naturally wants shrink over time.
  19. Question Trimless Channel Letter Fabrication

    the acrylic you see is just the tip of the iceberg: its a thicker piece of acrylic, usually .5"+, who's perimeter is hogged-down when routed face-down on the table. like a tophat. channel letter body formed per usual, acrylic "face" is then inserted & screw drilled into side to hold in place.
  20. Applying graphics to 4x8 sheet by ones self

    +1 Morph's comment: reduce error/effort by starting in the middle. its controltac, so don't be afraid to lift your graphic back up as you apply to reduce bubbles bunching up into wrinkles. peel the backing only so much as you go & keep tension on the un-peeled portion in the direction you're...
