CI-CHIP Dissolution Process
Solvent:
MEK (Methyl Ethyl Ketone)
Anone (Cyclohexanone)
TOL (Toluene)
1. When the temperature is between 28-32°C, the optimal ratio of solvents:MEK : Toluene : Anone = 7 : 2 : 1
2. When the temperature is over 32°C, the optimal ratio of solvents: MEK : Toluene : Anone = 6 : 2 : 2 or 5 : 2 : 3
3. The evaporation rate of solvent are directly related with temperature and printing speed, so the adjustment of solvent ratio should consider the situation at that time to make appropriate adjustments.
4. The ink temperature should not exceed 40°C upon dissolving, otherwise it will affect their brightness and liquidity. CI-Black and Red should be paid by particular attention.

※Recommendation: CI-CHIP shall be poured in slowly upon dissolution. After stirring completed, it can just use 80-150Mech net to filter.

Method of Inspection
Inspection for Hue, Concentration, Brightness, and Gloss:
Print white ink on black plastic sheets (or on transparent plastic sheets) and other color inks on white plastic sheets. When printing, the ink film thickness shall be applicator 0.3 i.e. 0.03m/m. After printed, compare the hue, concentration, brightness, and gloss between test samples and standard products.
Check and Test for Viscosity:
(1) Viscosimeter: Type BM AC/DC 1.5V X 4/400 MA
(2) Roter: NO:2 (for above 500cps NO:3)
(3) rpm (rotation speed): 62.5 rpm
(4) Room Temperature: Normal. Material Temperature: 26°C-34°C
Blocking Migration Test:
Take a piece of post-printed plastic sheet from item 1, after a 30-minute idling, clip a piece of white plastic sheet on the printed surface (for blocking test of white printing, clip a black or transparent plastic sheet on the printed surface).
Cut the plastic sheet or film, which is to be tested, into 5cm by 3.5cm; and cut the white clipping cloth into 6cm by 6cm. Put the surface to be printed against the white clipping cloth, stacking them up face-to-face; then clip them with plain glasses. On top, placing a heavy hammer weighing 120g/cm2, and put them into the oven at 50°C±2°C for 5 hours. After that, take them out of the oven, idling for 5 minutes. Tear down the white (black or transparent) plastic sheet from the printed plastic sheet which is to be tested, then determine the levels by visual observations according to the symptom of color migration. Normally, it will be determined into level 1-5; level 1 means Very Poor (worst color migration), and for level 5, Very Good (no influence).
Crocking Resistance Test:
Take a piece of post-printed plastic sheet from item 1, after a 24-hr idling in room temperature, cut it into 3cm by 22cm and then fix it on the crocking resistance testing machine. Use white 10P p/c sheet (clip black 10P p/c sheet upon white color test) to rub against white (or black) 10P p/c sheet. Then determine the levels by visual observations according to the symptom of crocking. Normally, it will be determined into level 1-5; level 1 means Very Poor (worst crocking), and for level 5, Very Good (no crocking).
Testing of Light Fastness:
Take a piece of post-printed plastic sheet from item 1, then put it into the Fade-O-Meter for light exposure. Afterward, take out the test pattern sheets to assess their degrees of discoloration (color fading) against a standard Blue Scale, and judge their light fastness good or bad.
Heat Resistance Test:
Take a piece of post-printed plastic sheet (film) from item 1, and put them into an oven under a condition of 180°C ± 2°C for 10 min. Then take it out to inspect their degree of color changing (degree of color fading). Afterward, assess the results for their heat resistance degrees which is generally assigned to value from 1 to 5 grades. Grade 1 is the worst (color is changed severely), while Grade 5 is the most excellent (color will not be changed).
Chemical Resistance Test:
(1)Testing for Acids or Alkalis Resistance: Take a piece of post-printed plastic sheet (film) from item 1, and dip it into the bath of 5% HCl or 10% NaOH for 1 hour, then take them out to assess their degree of color fading. On a comparison Scale 1-5, Number 1 is the worst (color is changed severely), while Number 5 is the most excellent (color will not be changed).
(2)Testing for Sulfur Resistance: Take a piece of post-printed plastic sheet (film) from item 1, and place them on the top of a H2S generator. After pressing for 15 minutes with flat glass on the top, then take them out to assess their degree of color fading. On a comparison Scale 1-5, Number 1 is the worst (color is changed severely), while Number 5 is the most excellent (color will not be changed).

※Remark: The Scale of Fastness for comparison is very important in the proper selection of appropriate pigments for coloring processes. Conditions of processing, end-uses application fields and the required properties of the finished product should be consulted before making a final selection of the optimal pigments.
