The new inks are installed. Can you start printing

production?

Once you have successfully loaded Artistri

your printer, there are a couple of steps you should follow before

starting to print your customers' production to ensure the best

print quality.

a. You will need to select the best waveform for Artistri

P1500 inks among those available on your printer. Your ink

distributor or a DuPont Field Marketing Specialist can assist

you (where available) in this task.

b. You will need to create color profiles for the Artistri

P1500 inks on your system so that colors are rendered

correctly on the fabrics you are printing for your customers.

If the fabric selection changes significantly seasonally or

by customer, create an Artistri

for each fabric type. For more details on color profile

generation, consult your printer OEM's Operations Manual,

or contact your ink distributor or a DuPont Field Marketing

Specialist to assist you.

c. Especially in the first few days of running Artistri

P1500 inks on your printer, it is advised that you monitor

closely the nozzle plate cleanliness during long runs to

establish a nozzle plate cleaning procedure and frequency

that is suitable for your production schedule and fabric mix.

Maintaining excellent print quality

Improper maintenance can negatively affect print quality

and shorten the life of the print heads. Pigment inks typically

contain higher amounts of solids than dye inks and may require

more frequent print head maintenance than dye inks. Frequent

nozzle checks are recommended to monitor the status of the

print heads and to maintain an in-control printing process.

Misdirected or missing nozzles should be cleared with a cleaning

cycle as soon as possible. If they are allowed to persist, they

will eventually become permanent missing nozzles and will

eventually lead to poor print quality. Never store the print head

in the capping station without thoroughly cleaning the nozzle

plate. Deposits of binder pigment inks left on the nozzle plate to

dry may be difficult to remove.

It is important to consider the effect production volumes or

new fabrics will have on print head maintenance and adjust

the frequency of print head cleaning appropriately to maintain

excellent print quality. When you are printing on fabrics with

a lot of lint or loose fibers, it may be necessary to increase the

cleaning frequency or perform manual cleaning with a lint-

free cloth soaked in deionized water or a compatible flush.

Monitor the condition of the nozzle plate and adjust auto-clean

frequency as necessary. Perform the daily, weekly and monthly

maintenance procedures for the capping station, wiper and

print head maintenance as recommended by your equipment's

OEM. If there are any concerns on maintaining print quality,

please contact your ink distributor or a DuPont Field Marketing

Specialist to assist you.

Optimizing process parameters for great color and

fastness with DuPont

™

Excellent fastness can be achieved with Artistri

and many commercial pretreatments. Some users also find

that the inks perform satisfactorily with their own proprietary

pretreatments. Keep in mind that acceptable print quality and

fastness (depending on end user requirements) may also be

possible on untreated fabrics. Pretreatment wet pickup on

the padder, pretreatment drying conditions and print fixation

conditions should be optimized with your pretreatment supplier

for your fabric selection. Your Ink distributor or DuPont Field

Service Specialist may also be able to recommend suitable

pretreatments for Artistri

Xite P1500 inks. Fixation in tenter

frames (dry heat forced air dryers) and calender dryers is

typically recommended. Adequate fixation can also be achieved

in systems using IR heaters. Pressing is not recommended as it

may yield lower fastness properties.

It is advised that you test your fabrics and optimize the

pretreatment application and print cure conditions for each

fabric type on your fixation unit. For medium weight (~150gsm)

cotton and cotton blends, you can start with fixation at 160-170°C

for 3 minutes. General guidance is to prolong fixation at lower

temperatures and shorten the time at higher temperatures.

The general rule of thumb is to add one minute of fixation time

when you decrease the temperature by 10°C. Please consult your

DuPont Technical Representation for pretreatment advice.

Removing Artistri

Xite P1500 Inks from your printer

When removing an ink from a printer/print head, it is a good practice

to print a last nozzle check on paper (if possible) before initiating

the flushing process. Retain that nozzle check as proof of print head

status. DuPont

F700 and DuPont

™

compatible with all Artistri

Xite P1500 inks. Your distributor can help

you select the best flushing solution for your printer.

After flushing the lines with DuPont flushing solution, introduce

deionized water to minimize any compatibility issues with a

subsequent ink. For more information on the procedure for

removing the Artistri

inks from your printer, please consult

DuPont's Artistri Ink Conversion Procedure and your printer

OEM's Operations Manual.

Printer/Print-head Storage with DuPont

DuPont

F700 and KF200 are NOT storage solutions.

™

They are intended for use as a system flush only. DuPont

recommendations for head storage when using Artistri

as follows:

a. In cases where the idle time is less than 7 days, it is

suggested that the user simply leave the ink in the system.

The head should be cleaned thoroughly and be fully

capped (sealed) when stored to prevent dripping from

nozzles or drying out. In addition, capping stations with

standing DI water or ink tend to maintain higher humidity

levels near the nozzles and have been shown to improve

nozzle re-start after the idle period.

b. In cases where the idle time is longer than 7 days, it is

suggested to flush the print head with a suitable DuPont

flushing solution and immediately load a cleaning or

storage solution (recommendation from the printer OEM)

for longer term storage. After loading the storage solution,

follow steps listed above in "less than 7 days idle".

Always consult your specific print-head/printer OEM's technical

documentation for the best practices for their individual products.
