1. Regular 97% white vs. double-up white to achieve 100% WHITE
2. White as a color toner REFLECTOR
The WhiteTRF foil is the Holy-Grail of foils because it's the only color that you can't print. It's always been assumed your "base" paper color is white. Remove the printed are and you gain white. But when your paper or surface color is other than white, now we have a problem, as color printers can only do "other than white". Sure there are a few new printers that have a white printing capability, but they're very expensive printers. The white FOIL has become the most powerful of all foils as it fill the need when you need to induce white.
Our white foil does a good job at converting black toner to about a 97% white image - not PURE white image. An interesting thing about our how our eyes get an 'average' reading and can tell us something is pure white when in reality it isn't. Look at the first double-image below. The left is one application of the white foil. It looks off-white or 'egg-shell' in tone. The right side has had a second application of white applied - big difference. However, when your eye does not have a reference to establish minor variations on white, your brain is tricked a bit into accepting the variation as pure white. Now look at the black background image on the right. Is it white or off-white?
1. DOUBLING-UP WHITE FOIL:
The "WhiteTRF" foil covers black toner to a level of about 95%, which means there is a very slight off-white, but glossy, effect. The human eye doesn't notice this very slight offset IF there isn't "pure white" reference next to it. For most applications, this 95% coverage is seen by your eye as pure white. Notice the difference between the two Budweiser images above. At first glance, the left image looks 'dingy' but that's only because of the transfer paper's shade and the pure-white reference from the "double-foiled" second Budweiser image. Now compare the left Budweiser image to the word "White" on the right-most image. The word "White" is the SAME brightness! It's just your eye not perceiving the 5% 'off-white' with the black background. Most of the time you don't need to be concerned about this 5% variance unless there is a pure-white painted reference near your graphic. Procedure is outlined in the Instruction Manual
2. WHITE AS A COLOR REFLECTOR:
All color toners from either a laser printer or a photo-static copier are transparent. When transferring to a transparent surface like glass, this can render a beautiful effect with transmissive light passing through the image, however, most of the time you'll want solid color. If the target location is white, no problem, but if the target location background is other than white (like the right-most image) the color toner (eg. the word 'Color') would be tinted by the background color to be barely readable. There are two methods to use the WhiteTRF under the color image to maintain vibrant color toners.
Method #1: REVERSE
Print the color image in reverse and apply the white foil. The WhiteTRF will fuse exactly to the shape of the color graphic. The process steps are outlined in the main Instruction Manual so it's not repeated here.
Method #2: OVER PRINT
Objective: Print a silhouette of the color image, add WhiteTRF to it, then reprint the color image on top of the WhiteTRF. To do this you'd duplicate the color graphic in the same spot on-screen but on a different 'Layer' (to be able to turn each one on or off). Next, convert one to an all black silhouette, add a 1pt line of white around the entire graphic to make it print a tad smaller, then add the WhiteTRF to the silhouette. The page is put back into the manual-feed tray and the full-size color image prints over the white base.
Color printers use 4 toner cartridges (Cyan, Magenta, Yellow and Black, referred to as CMYK or Process Color), and these toners are also TRANSLUCENT! To see SOLID color toner, there must be a white base to cast the correct color and vibrancy.
When printing on a color laser printers (and color copiers for that matter) it is always presumed that you're going to use white paper. The white paper is a reflector for the color toners as light does not reflect off the toner directly as you might think. Rather, light passes through the translucent color toners, bounces off the white paper which then carries the perceived color back to your eye.
In this photo above, we made two identical columns of color words. Both were printed on a color laser printer, created two dry-transfers and put on a black board, but in different ways. Notice how dark the right side came out. You can barely detect the bottom 3 words. This demonstrates just how destructive background colors are to transparent color toner. On the LEFT column we put the WhiteTRF foil UNDER the color toner before transferring.
Any target location that is not white will always be effected (tinted) by either brightness or color shift. A neutral gray color background would maintain color trueness, but the brightness will be reduced accordingly.
By adding the white foil, the white foil 'reflector' maintains overall color trueness.
There are two ways to use the WhiteTRF when working with color graphics. One method (like the black board above) is to print the graphic onto the transfer paper in MIRROR (reversed, called "Wrong Reading"), then add the WhiteTRF to the toner image, flip it around, add adhesive and make the transfer. The second method is when you have WHITE embedded into the graphic. This requires making a 'base' of white for the image. You print a black silhouette of the full image, add the white foil then back into the printer and print the original color image. Toners print great right on top of any foil.
