(72°F is ideal to prevent fluctuations in viscosity.)
If your customer wants to supply their own fragrance oil, it must meet the following requirements…
Fragrance Oil Requirements:
Fragrance oil must be water insoluble. Alcohols and glycols must be kept at an absolute minimum, as they are water-soluble. Avoid or minimize the use of aldehydes as these compounds may react with the microcapsule shell materials. Avoid materials that may cause pH changes. pH changes will interfere with the microencapsulation process.
Polar compounds tend to be water soluble including the following:
Avoid the above listed compounds if at all possible.
TransluScent™ is the newest method of advertising fragrances. It answers the call for an application of a fragranced product on conventional ink, varnish or aqueous coating application units. This product has great capabilities, as it can be printed directly over oil or water-based inks. The fragrance varnish, when scratched or rubbed, emits fragrance. Fragrance varnish does not require any specialized finishing equipment. This allows more printers the opportunity to produce fragrance promotions.
The TransluScent product line is supplied as a varnish or in powder form, which contain microencapsulated fragrance oil. Materials are supplied to printers in press ready form.
TransluScent is applied as any varnish, after ink application, but before drying ovens. The TransluScent formulation is applied by utilizing many different printing techniques, but the most common are Gravure, Flexo, and Aqueous Coating units.

Preparation for Printing:
Flexo Varnish and AQ Coating- The capsules in the varnish will settle during shipment, therefore, it must be thoroughly mixed prior to use. Using a mixing motor and blade, mix the slurry for 30 minutes. We recommend mixing with an air mixer 1/8 HP with a 3” marine prop mounted on an 18” stainless steel shaft. After 30 minutes of mixing the varnish is press ready. In the event that air is whipped into the varnish it must sit overnight to release the air and it must be remixed prior to use. If foaming occurs you may add a defoamer. Octynol or silicone based defoamers seem to work the best.
TransluScent Aqueous Coating Mixing Instructions:
After 30 minutes of mixing the coating is press ready. In the event that air is whipped into the varnish it must sit overnight to release the air and it must be remixed prior to use. To thicken the viscosity of the coating please contact us and we will send you the appropriate viscosity modifier. Mix the modifier in at 8% of the total weight of the slurry. Allow it to mix as outlined above for at least two hours. Test the viscosity at this point. If it is within your specifications then it is ready to go on press. If it is low continue to add in the compound at 2% of the total weight until you reach the desired viscosity. If the viscosity becomes too thick then you can add a very small amount of water to thin it slightly. DO NOT ADD TOO MUCH WATER. If you add too much water the scent of the coating will become very weak. Please contact us if you need any further instructions.
TransluScent Flexo Varnish Mixing Instructions:
Using a mixing motor and blade mix for 30 minutes. BE CAREFUL NOT TO CREATE A VORTEX. AIR MUST NOT BE WHIPPED INTO THE VARNISH. After 30 minutes of mixing the varnish is press ready. In the event that air is whipped into the varnish it must sit overnight to release the air and it must be remixed prior to use.
Start up and Running:
Check to see that the pan (if used), pumps, and hoses are clean of any residue. The best wash-up is with hot water. The lay-down of the varnish should be full and even. Insure that a sufficient amount of fragrance material is being deposited onto the paper before saving any product. Make adjustments as necessary during the run to maintain the desired coat weight. We also recommend using a diaphragm pump (rather than a gear pump) to mix the flexo varnish on longer runs to prevent separation of the capsules. The diaphragm pump will not rupture the capsules.
Cooling should be used on long runs (over 24 hours) of the flexo varnish. If the coating temperature is allowed to go over 85°F, rapid evaporation of water from the slurry occurs, which causes an increase in viscosity. Chilled water should be used to cool the slurry. Ideal slurry range temperature is 75-80°F. Please call us for technical advice if the viscosity is increasing due to high temperatures. You must maintain the correct capsule solids in the varnish to have a consistent fragrance level on the finished pieces.
