Why are paper trials important

to you, the printer?

Inkjet-treated

papers reduce ink

usage - reduced

cost of

consumables

Improved color

outcomes – pre-

print application

converting to

processed

color inkjet

Improved

overall workflow

performance

leading to better

throughput/

productivity




What happens in a typical

paper trial?

…the first paper to

work, wins!




Paper trial

challenges

Non-scripted trial with no clear

pre-trial or too general outcomes

established.

The paper industry’s eagerness to

secure a foothold – throwing rolls

at the opportunity

Asset owners level of expertise – Is

it OEM approved?, we’ll try just

about anything or what I got works

OK, can’t interrupt the work.

Trial results typically yes/no with

little useful information for

stakeholders

Early adopters

experience trial

fatigue as a result

of poorly

conducted trials




Drivers for Substrate Change /

Acceptance Improved overall workflow Performance

leading to better throughput/productivity

Improved color outcomes – pre-print application converting to processed color inkjet.

Reduced cost of consumables

IJ treated papers reduce ink usage and better color outcomes.




Understanding

those variables

will ensure a

successful paper

trial, eliminating

wasted time and

consumable costs.

The success of

aqueous inkjet

production depends

on understanding

your process and all

the variables.

Trial

Preparation




Focus on the

Finished Product

When preparing for an inkjet paper trial,

think about the finished product first.

What is the end product?

• direct mail, transactional, trans promo,

book, marketing, newspaper

Finishing needs?

• trim, score, binding, fold, inserting

Expected color and print quality?

Color match to other devices?




IdentifyPrintCoverage




Identify Your Ink

Know the colorant of your ink

Pigment

Dye

Understand the ink composition

Aqueous = water

Understand the impact it has

with various paper surfaces




Paper

ChoicesBased on print quality (PQ) or

price ($)

PQ and $ affect each other

Acceptable PQ= $ uncoated

Better PQ= $$ inkjet treated

High PQ= $$$ Inkjet Treated




Paper

ChoicesBased on TIC

(total ink coverage) TIC and paper surface affect

print quality

Ink dives faster into $ than $$

and $$$ papers

$ papers require more ink to

“build up” colorant on the

surface than $$ and $$$. Also

cockle and mottle issues




Paper Choices Affect Image Quality

Flat or low image definition

Washed out or dirty color

Color shift print to print

Side to side color differences

Print mottle

Show thru

Small text legibility 4 to 6pt

Dot gain, lower image detail

Color gamut, reproducible colors




Trial

Preparation




Trial Preparation

Prepare items needed

previous to trial

Schedule time with

production

Graphic files to be ran

Check if paper profiles are

needed

Stage paper 24-48 hours

before run




Trial Preparation

Prepare a trial outline for

printer and paper supplier

Files, coverage, paper specs,

TAPPI roll info, profile name,

run speeds, heat settings

and print quality

expectations




Trial Preparation

Pre-trial meeting

with group Set print expectations




Trial Preparation

Create job folder

for all samples and

documentation




Paper Conditions




Paper Conditions

Verify paper

width and

core size




Paper Conditions

Paper check at

the dock

No telescoping or

crushed cores

No paper wrinkles

or baggy rolls




Paper Conditions

Acclimate paper

to print

environment

Min 24 to 48

before printing




Paper Conditions

Retain TAPPI

paper label




Time

Scheduling




Time Scheduling

Scheduling time based

on trial needs Est. 2-3 hours for one test roll

Add 45 -1 hour for additional rolls

2-3 hours for each new paper spec

addition for custom profile creation

If customer is present, add 45 min

to each additional test roll




Time Scheduling

Review prints 2-3 hrs

after entire trial Allows print settle time-color and paper
