Sublimation Adventure: Alice’s Adventures in Wonderland: Lewis Carroll ‘No, no! The adventures first,’ said the Gryphon in an impatient tone: ‘explanations take such a dreadful time.’ By David Gross Photo 1 nd so it is with the world of sublimation. One of my favorite applications for sublimation has always been tile murals. These come in many forms, including kitchen backsplashes, bathroom murals, glass floor murals, bar murals, and many more. I installed my first mural about 14 years ago after walking into the front door of our local Lowe’s and asking if I could install a custom back splash in one of their demo kitchens. (I can only guess what they thought.) They accepted, and with their help on how to grout—mission accomplished! (See Photo 1) Ever since, I’ve been preaching about murals and how the market has exploded with works of art that are nothing short of amazing. The rest is history. Reprinted from THE SUBLIMATION ALMANAC 2008 Q&A Looking Up As Captain Kirk explores the final frontier, we look to the ceiling as the great untapped resource to point our digital decorating resources. Applications range from home theatres, game rooms, sports bars, day cares, examining rooms, waiting rooms, and retail stores—the list is endless. Just think of the serenity of looking up at a relaxing scene the next time you visit the dentist! After much research, we recently began offering our DyeTrans ceiling tiles—a poly fiber material that has excellent sublimation characteristics, superior acoustic properties, and is easily cut. Since ceiling tiles are usually either 2’ x 4’ or 2’ x 2’, you might not have the equipment needed to print and transfer at this Photo 2 size. That’s where our Print Services Department can help out by printing and/or pressing the job for you. After several successful jobs, you might decide that it makes sense to invest in a large-format sublimation system like the DyeTrans 9880 and a large flat press like the Geo Knight MAXI•PRESS and produce them yourself. The Project: A Floor And Ceiling Tile Mural Always trying to push the limits, we chose a unique project to highlight sublimation at our annual open house this past August. At the entrance to our foyer, we installed a combination floor and ceiling tile mural. Step One: Site Survey Our foyer at Condé Systems was perfect for this project. (See Photo 2) The mural area for our ceiling is about 12’ x 14’ and the floor area is about 8’ x 11’. Ceiling tiles were 24” x 24” (except at the outer edges of the mural where each was cut to size) and the floor tiles were 12” x 12” Bison tempered glass tiles. Since it was a temporary installation, we used our interlocking base grids for the floor tiles instead of grouting them. Planning at this step is always critical—you must map the exact overall dimensions of each mural and determine tile overlap/separation. Reprinted from THE SUBLIMATION ALMANAC 2008 Q&A Photo 3 Resolution The most important step in turning an image into a mural is resolution. An image is just a block of dots. There are so many dots horizontal and so many dots vertical. When you decide on a print size then you have resolution which is number of dots (Horizontal or vertical) divided by the number of inches for the print size. For example, let’s say an 8MB digital camera captures a block of dots at 3264x2448 dots. If we, say, want to print this at a print size of 20” x 15” then that puts us at a resolution of 163.2 dots per inch (3264/20 or 2248/15) We almost always maintain proportionality. So you can see, we need lots of dots to build big murals. So, also get the highest resolution you can. If you still need more resolution, then we turn to software for image enhancement (see the Resolution Enhancement Software sidebar). Step Two: Image Selection Ceiling Mural The ceiling mural image was purchased from iStockphoto.com at the largest size available, which was approximately 10” x 12” at 300dpi. (See Photo 3) Once we had the image, we carefully measured the ceiling area and the gap between the tiles where the image would not be visible. These are the key elements in determining your image size and placement. We then used Genuine Fractals 5 to enlarge the image to just a bit bigger than the needed size and adjusted the resolution to 150dpi. We have found that 150dpi is an acceptable resolution for soft, fibrous substrates. Doing this also results in a smaller file size— one that doesn’t bog our computer down more than it has to. Had we kept the file at 300dpi, the image would’ve taken twice as long for the computer to edit, tile, and even print. Photo 4 Floor Mural This image was also purchased from iStockphoto. We wanted a floor image that complemented the ceiling image, and we felt the waterfall really tied it together. We enlarged the image to 8’ x 11’ and adjusted the resolution to 150dpi. We usually consider 200dpi to be the minimum standard for most hard substrates, but 150dpi was determined to be sharp and acceptable, since this image was going to be viewed through textured glass. Photo 5 Tiling Software To tile an image, there are two ways to go: software tiling or manual tiling. For this project, we used Wasatch SoftRip for both tiling and printing. Other software solutions include Mural 8. It is also popular to manually tile using Photoshop or CorelDRAW.We have instructions and templates on our website www.conde.com in the support area. Reprinted from THE SUBLIMATION ALMANAC 2008 Q&A Step Three: Image Prep And Tiling Ceiling Mural Our ceiling was unique since the tiles on the outside border were not full size. That means that cutting would have to be involved. To properly tile the image, our method involves sizing the image and image canvas in Photoshop, then using the tiling program for nothing but tiling. (See Photo 4) In other words, we already have the image and canvas at proper size. Then when we tile it, we get properly sized tiles and only partial images on the outside tiles with the rest left blank. Once the tiling was correct, we reversed the image. Tile overlap is a feature used when tiles are installed right up against each other with no grout line. The outsides of each tile repeat themselves, so that when transferred, the image lines up perfectly from the end of one tile to the beginning of the next with no gap. For our ceiling application, this was not necessary. There was a 1/4” gap between each tile where no image was visible (similar to a grout line) so that means that the bleed areas not transferred to the tile are simply discarded, as they wouldn’t be visible anyway. Floor Mural For sizing, the same principles applied, with much more tolerance and freeform. The floor mural was installed using interlocking base grids—so, unlike the ceiling, we could make it whatever size we wanted. All we did was multiply our dimensions to find a good size that was proportionate and consumed a lot of the floor area. The interlocking base grids leave a 1/8” gap between tiles. This means the same method used for the ceiling mural would also work here. The missing 1/8” could simply be discarded, and it would line the image up properly. So we simply sized and tiled the image with 12 1/4” square tiles. Perfect! (See Photo 5) Remember that when you print images for glass tiles, you do not mirror the image—even the experienced sublimator can make this mistake. Step Four: Printing Once the image is tiled, we did some test printing to confirm size and color. I recommend that you do a test tile for color and then print all tiles and confirm size and layout before pressing. This advice will save you countless hours and money. I also recommend archiving the exact print job by turning on the save print job feature. See my Photo 6 top 50 tips and tricks on my web site (from The Sublimation Almanac 2008). When printing the images for both murals, we made sure to annotate the prints with their row and column (1A, 2B, etc.) so that they would stay in order during the transfer process. This is a feature in Wasatch, but could even be done manually if your program doesn’t have it. Ceiling Mural We produced our prints in 360dpi (droplets per inch) print mode on the Mutoh RJ-900 large-format inkjet printer. This print mode lays less ink down than 720dpi mode (the default mode that most printers print in) and prints significantly faster. The lesser amount of ink is acceptable since we were printing on TexPrint high-release paper and transferring onto the ceiling tiles, which are a “thirsty” substrate (one that accepts lots of sublimation ink). Condé’s Print Services Department recommends printing transfers for fabrics, soft items, and fibrous substrates in this print mode. Photo 7 Reprinted from THE SUBLIMATION ALMANAC 2008 Q&A Floor Mural We also used the Mutoh RJ-900 with TexPrint paper, this time in the 720dpi print mode. This lays more ink down and provides sharper resolution on the paper and on the substrate. Condé’s Print Services Department factors these things in greatly when we sublimate to hard substrates. Step Five: Pressing Ceiling Mural Now that the prints were out of the printer, the transfer process was easy. The ceiling tiles are very easy to image, since they’re basically felt material compressed into a rigid board (Temp: 400 degrees; Time: 1:30; Pressure: Medium). They come out of the press soft and flexible, but harden as they cool. They cool off quickly, so be sure to lay them down flat or else they’ll reconstitute into a warped shape. Utilizing the 40” x 64” air-powered MAXI•PRESS, we were able to comfortably press two 24” x 24” ceiling tiles at a time. For pieces that required cutting, we either pre-cut the tile using the original ceiling tile as a template (See Photo 6) or we ganged several small prints onto a full piece of material, then cut them to shape during installation. Floor Mural Large presses like the MAXI•PRESS are excellent for producing large murals. The large platen can comfortably fit six 12” x 12” tiles per pressing—dramatically reducing production time. The pneumatic air pressure also assured us that pressure would be consistent once the press was set. The tiles were pressed with the transfer face up and the ceiling tile face down. This method of pressing (the substrate on top of the transfer) is only applicable to items that transmit lots of heat such as ceramic tile, metal, and FRP. Fabric, for example, absorbs far too much heat and can’t be done this way. We pressed only four tiles at a time for quality control and inspection reasons. We closely inspected each tile and ensured that Photo 8 Reprinted from THE SUBLIMATION ALMANAC 2008 Q&A our process was consistent before and after each press. Step Six: Installation Ceiling Mural As we installed the tiles, we laid the original ceiling tiles on top so as to weigh the new tiles down and keep them nice and flat. This is also useful if you don’t plan on the mural being a permanent fixture. (See Photo 7) The most difficult part of installation was cutting around the light fixtures. *A qualified technician carefully removed the light fixture and separated it from the original tile. Then using the original tile as a template, we cut the hole for the light fixture by hand with a razor knife. This was difficult to do because of the circular shape, and because the ceiling tiles are actually very rigid and take several passes to cut completely through. Once this was done, the new tiles were installed and the light fixtures fit into them. This time the Photo 9 original tiles had to be stowed elsewhere since the box of the light fixture didn’t allow us to stack them. Floor Mural For the floor tile mural, we used the interlocking base grid and glued the tiles in place with E6000 self-leveling glue. Available at Condé, this clear glue did an excellent job of securing the tile to the base, since not all the tiles are exactly the same size. Once glued in, tiles must be left to sit for 24 hours so that the glue can dry and cure. Once the glue cures and the tiles are securely in their holders, the tiles are connected together. We have used this kind of installation for many years at trade shows with excellent results. Measure and tape off the corners of your intended placement area. This is very important, since as the mural is assembled, it will become heavy and very difficult to move—especially over carpet. Assemble from one side to the other, preferably from top to bottom. One excellent tool to have on hand is a rubber hammer. We laid out one entire row at a time face down, pounding the joining snaps together with the hammer. This is much less painless than snapping them in with your fingers. (See Photo 8) Once an entire row was adjoined, we flipped it over and joined the upper snaps to the row above it simply by stepping on them with our feet. Using this method, installation took about an hour. Conclusion Ceiling Mural Once installation was finished, we had a full-coverage image over the entire ceiling area. With some pleasant floor lighting and additional plant décor, the mural came to life and provided the exciting and enveloping effect of being underneath a thick forest canopy.

(See Photos 10 & 11) Resolution Enhancement Software Once you have done all you can to get a highresolution image, then you turn to programs like Genuine Fractals (www.ononesoftware.com) to help achieve a respectable resolution.We recommend 150dpi for soft substrates and 200dpi for hard substrates. This add-on, for Photoshop and Photoshop Elements, intelligently re-samples the image to bring out more apparent resolution. It is only a band-aid and not a substitute for getting the best image possible going in. Reprinted from THE SUBLIMATION ALMANAC 2008 Q&A
