SELECTION 78 colors are unleaded inglaze colors for porcelain, bone china, chemical bone china and stoneware.
SELECTION 78 colors are technically lead and cadmium free（exception the item code that started with "62" that contained Pb）, with no more than 0.1% lead and 0.03% cadmium due to contamination on production.
SELECTION 78 gold containing colors was developed using advance technology and which have the following advantages.
They are intense, vivid and have wide range of color tone.
They are very stable in high temperature firing up to 1,230C.
They have a high degree of transparency and clarity.
They can be used as magenta and can improve four-color printing.

APPLICATION
Selection 78 series is suitable for screen transfer printing; direct printing, spraying, pad printing and hand painting.
MESH SIZE
Recommend mesh sizes are 180-300 mesh（71-120T）for all screen applications.
MEDIUM RATIO
| Color： |
Medium= 10:6.5-8 |
| Flux： |
Medium= 10:10-12 |
Lead free colors absorb any moisture easily therefore powder colors should be kept in a dry place. We recommend drying the color powder before using.
MISCIBILITY
Selection 78 colors can be mixed with each other in any proportions basically. To obtain pastel color tone 78201 white is suitable. 78101 flux is suitable for mixing and overprinting. Overprinting 78101 flux can improve color stability in high firing temperature.
FOUR COLOR PRINTING
Four colors
| Yellow |
78312 |
| Magenta |
78907 reddish from 1,180 up to 1,230 |

| Cyan |
78804 deep |
| Black |

| Flux |
78101 standard flux for mixing and overprinting |
To determine the proper four colors, we recommend testing under your firing conditions.
To lighten colors, 78101 flux is recommended mixing with four color.
Printing order
Yellow --> Magenta -->Cyan --> Black --> 78101 Flux
Overprinting 78101 Flux does not change color tone and can improve color stability in high firing temperature.
