Background of the Study

 Highlighter is an essential stationary item for students
as well as working people. In school, students and
teachers use highlighter to mark words they don’t
understand, things to memorize, terms to research,
areas of special interest and things they think will be
on the test.
 Ink is one of the most important components of
writing tool today. All inks consist of a colorant and a
vehicle . The selection of ink is an important decision
one must make in terms of the performance of one’s
pen.
Background of the Study

 Achiote (Bixa Orellana L.) is a shrub or small tree
commonly found in the Philippines and better known
as atsuwete or achuete. Its fruit is best know for the
natural pigment, Achiote.
 It is this dye that interest the researcher to pursue the
possibility of transforming it into an alternative source
of highlighter ink.
 These are the primary reasons why there is a need to
look for alternative sources of substances used to
make inks.
Statement of the Problem

 What are the characteristics of the different
samples of highlighter ink in terms of:
Color
Odor
 Texture?

 The quality of the ink, in terms of color, odor and
texture has the kind of specifications that
maximizes the writing experience of the writer.
As such it has the following characteristics:
 The alternative ink has the ability to be
permanent.
 The ink does not dry immediately due to the
viscosity of the ink
Statement of the Problem

• Which of the different ink samples
produced is most acceptable?
• Is there a significant difference on
the characteristics and
acceptability of the different
samples of highlighter ink?
Scope and Delimitations

 The researchers used Achiote seeds as the subject sample
of their study on the possible source of ink for highlighters.
In this study, there is no specific variety of Achiote plant is
preferred for the source of ink. All the available local
varieties of Achiote plant can be tapped as possible
sources.
 The method of study is experimental; thus, it will involve
some laboratory trial and error methods of sampling to
determine the appropriate sample for a workable
highlighter ink.
Procedures

1. Gathering of materials and chemicals to be
used.
2. Measuring the amount of Achiote powder and
chemicals.
3. Mixing the desired amount of powder and
chemical.
4. The product is then ready for product
evaluation.
Statistical Tools

 Mean – used to measure the characteristics of
the ink.
Where:
= sample mean
Xi= values in the set
n = sample size
 Kruskal-Wallis – to test the null hypotheses
Where:
N= sample size
T= sum of ranks 1th sample
n= total # of observations
