It is the basis for a good result, so you must ensure that all materials guarantee professional results.
1.Sublimation inks : Use quality inks to achieve rich, vivid colors, sharp contours and durability in your prints.
2.Sublimation Paper: Paper is a very important time to ensure that the ink transfer element is performed correctly. If you use a low quality paper chances are your design run out of ink in some areas and causing white spots appear brighter areas.

Check the status of your printer
It is very important to the problem of the appearance of design points to check if our head printer has an obstruction.
Sublimation inks are water-based, so that it is possible that drying ink is in the head and block. If this occurs, the problem of points (either white or another color) in the sublimation comes from the printing stage, since it is the printer that is occurring.

Next step: ironing
If the above are not the cause of the stains / colored dots likely then the source of the problem is on your plate.
Sublimation, it is very important that all your equipment is clean to avoid problems with color. If appropriate measures are not taken, it is likely that your iron plate is soiled with ink from previous sublimations and those remains are transferred into the new sublimations you make. To avoid this, we always recommend using sublimation protective paper which tile with white spots on sublimation between the printed sublimation paper and the hot plate of the iron.
It is also important to test the hot plate temperature distributed evenly, as if hot areas where less will fail color transfer from the sublimation paper to the object that you are customizing. To check the temperature of your iron you can use a digital thermometer and if you see that your plate does not heat the whole area alike need to change the resistance or even buy a new plate.
To conclude this section, remember that you should always follow ironing parameters recommended by the manufacturer of blank products since due to its composition and characteristics each has different indications.
