Sublimation Process
Customize: Choose any picture, illustration or other graphic image. Sublimation works for any variety of color combinations from black and white to full color. You can scan in your own conventional photo prints, use a digital camera or select from a variety of stock images to include names, dates, scores or other custom information. Run color correction software. At this point you will notice your colors have become very muted. This is to compensate for the brightening that occurs during the sublimation process.

Print: Select the printer into which you have inserted the special sublimation ink cartridges. Print True Pix paper just as you would a normal page. Multiple transfers can be printed or similar single pages with name change, etc. for personalization Remember, the output will look considerably duller than a normal color print in order to compensate for the sublimation brightening.

Transfer: Preheat your heat press per the manufacturer's instructions (specs & tutorial for applying transfers.) Then, position your piece of True Pix Transfer paper on the press and apply pressure as indicated for the appropriate amount of time. Next, lift the press and carefully remove the transfer. Finally, assemble the clock, clipboard or other components and you are finished. Practice makes perfect!

TIPS ON GETTING THE BEST RESULTS FROM SUBLIMATION
PRE-HEATING THE TRANSFER
Varying storage conditions may have an effect on the moisture content of transfer paper. To eliminate moisture from transfers, place the printed transfer 2" - 3" below the heat platen for 20-40 seconds. The colors of the sublimation transfer may appear washed out. This is normal, and the desired result of color adjustment for the transfer process.

PREPARING THE SUBSTRATE

Remember to peel the transparent protective film off the surface of the substrate (if applicable) and check to see that you are working with a clean, lint-free surface. It is possible to damage the edge of a blank part if one picks at the corner or edge with a fingernail or sharp instrument to try to remove the protective film. We have found the best way to remove the film and minimize the risk of damage is to use the tacky side of a piece of protective film recently removed from another part. Drag the tacky side of the film along the top surface of the tile starting at the corner and moving towards the center of the tile. If you do not have an extra piece of film handy, you can use the pad of your thumb or forefinger in the same manner to peel back the edge.

Adding a "bleed" to your artwork will help you to align your transfers. To create a bleed, enlarge your background artwork so that it is 1/16" to 1/8" larger than your blank piece. Place your blank product face down over the transfer. You will know that the blank piece is properly aligned when you can see an even amount of ink all the way around the edge. Fold tow edges of the paper over to the back of the product, and attach it to the back with heat resistant tape to hold it in position.

Sometimes a "double image" results when the transfer moves across the sublimatable surface while it is still hot, usually when the press is lifted or while removing the transfer from the sublimation surface. To prevent this, it is recommended to always use a transfer sheet that is larger than the surface you are sublimating onto. Ideally, the paper should be large enough to secure it to the backside of your sublimatable blank with heat resistant tape.

A small amount of edge foil will be left on the edges of plaques, paper-weights and picture frames after the peel coat is removed. This should be removed from the sublimatable surface by scraping the edge with your fingernail, or by using a mild household cleaner and a paper towel. Do not tape to the foiled edge of a plaque or paperweight as it may pull the foil off when removed. If possible, allow the piece to cool slightly before removing the transfer and tape.

TEMPERATURE AND DWELL TIMES
A temperature of 400°F is recommended for all products. Use moderate to heavy pressure - it should require some effort to close your heat press. Time and temperature may vary depending on your heat press and the thickness of the blank material. Dwell times can be increased or reduced in 5-10 second increments until you find the time that results in the clearest image. The times shown below will provide a general starting point. Please refer to the documentation from your ink suppliers for more information on temperature and dwell time.

FR Plastic (name badges, bag tags, etc.): 60-70 seconds
FR Plastic for outdoor use (license plates): 80-90 seconds*
Hardboard (clipboards, coasters, etc.): 60-70 seconds
MDF (plaques, paperwights, etc.): 80-90 seconds
Phenolic: 45-55 seconds
Aluminum (sheet stock and jewelry): 45-55 seconds
Aluminum (bookmarks, face down): 60-70 seconds
Car Flags: 25-35 seconds

*Laboratory research has shown that using a longer dwell time can extend outdoor life. While these sublimatable products feature UV absorbers to extend outdoor life, they are no intended for permanent outdoor use. Fading will occur over time depending on the brand of sublimation ink used and outdoor environment.

Large parts will require a longer dwell time to produce optimal color. For any pieces that are larger than 9"x12", we recommend increasing the dwell time by 15 seconds over the recommended setting for that substrate. If necessary, increase the dwell time 10 second increments until you archieve optimum color.

Please exercise extreme caution when removing finished items from your heat press. We recommend using an oven mitt or rag when removing products from your heat press. Warping can be minimized by allowing products to cool face down on a firm surface, and by placing a weighted object on the back of the product. If warping is servere, the sublimated piece can be heated a second time from the back side and allowed to cool. Do not bend products while they are still hot, as this can damage the substrate and your sublimated image.

A blowout refers to an image whose colors have been "blown out" of its boarders and appear smudged. The primary causes of blowouts are uneven heating, overheating and excessive pressure. heat press accessories, such as a rubber pad or a teflon sheet covering a transfer held in place with heat resistant tape will prevent a blowout of your image by lessening the variance in temperature across the surface. Anytime your choose rubber pads instead of a teflon sheet to prevent a blowout, increase the temperature 25 degrees and the dwell time in 15 second increments until your achieve optimum color.

TWO-SIDED SUBSTRATES
While it is possible to sublimate both sides of certain materials at the same time, it is not recommended on any Unisub material except aluminum. Sublimate the first side of the material as normal. Allow it to cool completely before taping your transfer for the second side. Use an oversized sheet of paper for the second side, and try to attach heat-resistant tape only to the paper.

CURING RECOMMENDATIONS
Although pre-cut blanks can be purchased through your distributor, FR Plastic sheet stock can be cut, routed or beveled either before or after sublimation using carbide tooling. We recommend using either a router bit designed for acrylic or a multi-tooth saw blade designed for plastic.

We do not recommend shearing for FR Plastic. The fiberglass content of this material will damage your shear blade. Also, we do not recommend laser cutting because the edges of the plastic will be charred. Hardboard products may be cut using laster engraving equipment. The peel coat or masking should be left on the products until after cutting. Consult your user manual or laser engraving equipment manufacturer for power settings for your machine.

STORING FINISHED PRODUCTS
Special care must be taken when storing or packaging finished sublimated products. If sublimated pieces are placed in direct contact with other sublimatable materials or with any type of synthetic material, the inks will migrate from the sublimated piece to the synthetic material over time. Do not stack finished pieces face-to-face, either hot or cool. Do not wrap finished pieces in shrink-wrap or place them in plastic bags for shipping. We recommend that you use a paper sheet between stacked items, or wrap pieces in paper for shipping.

JEWELRY ASSEMBLY
Once cool, jewelry pieces can be assembled by hand or with needlenose pliers. The pieces can be attached to a necklace or charm bracelet with a bale (included with these pieces). Open the pointed end of the bale with your fingernails or pliers. Put the pointed end through the mounting hole on the jewelry piece, and hang the wide end over the necklace or a charm bracelet link. Pinch the bail with your fingers or pliers to close it shut.

Earring hooks attach directly to the jewelry pieces without additional hardware. The loop on the end of the earring hook is opened slightly to allow you to slip it through the mounting hole on the jewelry. The point of the hook should point away from the sublimated face of the earring.

Dye Sublimation Transfer Variables
Because you can imprint to a variety of surfaces and substrates, you will need to take all variables of the surface into account when selecting time, temperature and pressure.

Substrate Surface Variables Include

  • Thickness of surface
  • Surface texture
  • Surface size
  • Surface color
  • How fast the surface absorbs heat
  • Accuracy of heat press (time, temperature and pressure)


  • Preparing Your Art Work and Transfer Paper
    Print your images approximately 1/4” larger than the size of the substrate you are transferring to. This allows a margin of error when aligning everything under the heat press platen. Software templates are available for many of our substrates and we also offer add-on software with pre-built templates for a variety of substrates. Use the recommended paper and substrates for sublimation transfers. Moisture and humidity will cause undesirable results (color shifts, bleeding and uneven transfers) with the sublimation process. To avoid these problems, keep your paper or fabric in a dry place.

    If you suspect moisture, try these techniques:

  • Place paper on the raised pedestal bottom of the press and let it dry under the heat platen. Don’t close the heat platen!

  • Prepress fabric for 10 seconds before transferring.

  • Use a fresh, non-textured paper towel behind the transfer sheet.


  • Protect Your Heat Press
    The Temp/Time/Pressure settings listed in this document are general guidelines. Sublimation transfer is not an exact science… you may find it necessary to experiment with these settings to obtain ideal results.

    It is important to protect the rubber pad that is attached to the raised pedestal bottom of the heat press. The same is true for the rubber pad found in a mug press. Covering the pad with a protective sheet of paper, a paper towel or a brown Teflon sheet will prevent sublimation ink from being absorbed into it.

    If you use paper - Choose an inexpensive white bond paper or a roll of white paper (cut as needed)… discard after each pressing.
    If you use a paper towel - Choose an inexpensive, white, non-textured brand (the texture will leave a pattern on the substrate)… discard after each pressing.
    If you use a brown Teflon sheet - This is a reusable sheet that should be cleaned with alcohol after each pressing.

    After transferring the image to the substrate, promptly remove the transfer paper. Do not stack the transferred items with anything else until they have completely cooled. Any paper residue left on the substrate after transferring can be removed with isopropyl alcohol.
