The bubbles show up better when you view the piece at an angle.</p> <p>Dave</p> <hr /><a name="a304_19"></a><p><b>From: LaZerDude (C_BURKE)</b> [<a href="lmessages.php?webtag=EE&msg=304.19">#19</a>]<br /> 19 Mar 2005<br /><b>To: UCONN Dave &amp; Lynn too (DANDL48)</b> [<a href="lmessages.php?webtag=EE&msg=304.18">#18</a>] 19 Mar 2005</p> <p>Dave,</p> <p> Thanks for the tip. I think I am making progress.</p> <p> What I have done at this point is cut the rapid mask into approximately 3" squares. I then remove both of the carrier sheets leaving only the mask. This allows me to lay the mask flatter with few air bubble. <br /> Next I laser etch the logo, I then blasted it. The longest part of the process was removing the carrier sheets.<br /> The attached photo is the result. It still needs some refining, but I'm getting there I think.<br /> The question I have now is, is the laser resist, basically the rapid mask with out the carrier sheets?</p> <p>Thanks</p> <p> </p> <hr /><a name="a304_20"></a><p><b>From: precisionlaser</b> [<a href="lmessages.php?webtag=EE&msg=304.20">#20</a>]<br /> 19 Mar 2005<br /><b>To: LaZerDude (C_BURKE)</b> [<a href="lmessages.php?webtag=EE&msg=304.19">#19</a>] 19 Mar 2005</p> <p>Hi, Chuck...</p> <p>Laser Tape is not the same thing as RapidMask without the slip sheet.</p> <p>Laser Tape (and Rayzist's LaserMask) is a non-PVC film (a form of non-PVC vinyl?) which is not UV-sensitive. RapidMask is a different product chemically (I think polymer based, but am not sure) and of course is UV-sensitive.</p> <p>With a 6:1 price ratio, it's safe to say that they are two completely different products...</p> <p>Mark </p><hr /><p>Message 304.21 was deleted</p> <hr /><a name="a304_22"></a><p><b>From: UCONN Dave &amp; Lynn too (DANDL48)</b> [<a href="lmessages.php?webtag=EE&msg=304.22">#22</a>]<br /> 19 Mar 2005<br /><b>To: LaZerDude (C_BURKE)</b> [<a href="lmessages.php?webtag=EE&msg=304.19">#19</a>] 19 Mar 2005</p> <p>Chuck,</p> <p>Mark basically covered it all.

My recollection is that the HT (4 mil) is equivalent in feel to the LaserTape, which isn't surprising, given that they're the same thickness. I also think that the carrier sheets are responsible for much of the feel, as mentioned in an another thread. Now, the RapidMask HD seems very pliable to me (2 mil) and I'd think that this is the stuff to use on compound curves.</p> <p>I wonder if you warmed the mask with a blow dryer once it's applied and after the carrier is removed, if that would cause it to conform to the curves better. Just a thought.</p> <p>Mark</p><hr /><a name="a304_25"></a><p><b>From: LaZerDude (C_BURKE)</b> [<a href="lmessages.php?webtag=EE&msg=304.25">#25</a>]<br /> 20 Mar 2005<br /><b>To: precisionlaser</b> [<a href="lmessages.php?webtag=EE&msg=304.24">#24</a>] 20 Mar 2005</p> <p>A blow drier huh?

Do you use the same exposure time for RapidMask HT and HD?</p> <p>Which product are you finding that you use more often -- HD or HT?</p> <p>What printer and inks are you using to print your negative image on the AccuBlack film?</p> <p>I recall from an earlier conversation that there was a substrate that the RapidMask would leave an actual discoloration mark where it was applied. Am I correct in recalling that that substrate was marble?</p> <p>ÃƒÆ’Ã†â€™ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â </p><p class="edit_text">EDITED: 9 Apr 2005 by DATAKES</p> <hr /><a name="a304_29"></a><p><b>From: UCONN Dave &amp; Lynn too (DANDL48)</b> [<a href="lmessages.php?webtag=EE&msg=304.29">#29</a>]<br /> 9 Apr 2005<br /><b>To: Engravin' Dave (DATAKES)</b> [<a href="lmessages.php?webtag=EE&msg=304.28">#28</a>] 9 Apr 2005</p> <p>David</p> <p>You are correct about the marble. If I blast and than paint the mable and it is exposed to sunlight, the marble area that is not under the masking tape takes on shape of the exposed resist even though it is under paint. No problem with it if I spray paint outside and immediately bring it inside and put it in a dark place. We use HD about 90? of the time when not using the laser to burn the resist. Only with marble do I use the thicker resist sind I like to go deeper in marble.</p> <p>We use the laterlite exposure system and expose both for 4 min. Wish I could afford the system you have.</p> <p>We use the HP 5550 deskjet with their standard black ink on Accublack velum.</p> <p>Dave</p> <hr /><p align="center">Show messages:  <a href="lmessages.php?webtag=EE&msg=304.1">1-16</a>  17-29</p> <h4><a href="lthread_list.php?webtag=EE">Back to thread list</a> | <a href="llogout.php?webtag=EE">Login</a></h4> <h6>© 2025 <a href="http://www.beehiveforum.net/" target="_blank">Project Beehive Forum</a></h6> </body>
