FORMULASI TINTA WARNA KHUSUS FLEXOGRAPHY WATER BASED UNTUK PRODUK KEMASAN CORRUGATED DI PT PROKEMAS ADHIKARI KREASI

With the advancement of technology, innovations in ink formulations continue to
evolve to meet the increasingly complex market demands. PT DIC Graphics is a
leading chemical company in the printing ink industry and has several implants in
printing companies, one of which is at PT Prokemas Adhikari Kreasi, which
operates in the field of corrugated box printing. This research focuses on identifying
issues, including the unknown values of viscosity, density, and CIE Lab* in the
formulated ink. The problem statement and research objectives are directed
towards addressing the discrepancy between the printed color and the standards
desired by the customers. The data collection techniques for this research include
observation, literature review, interviews, and testing. Observations were made at
the DIC Implant of PT Prokemas Adhikari Kreasi, while the literature review
involved various scientific reference sources. Testing was conducted by creating
ink formulas according to customer standards, followed by viscosity testing using
Zahn cup 4, as well as density and CIE Lab* value testing using a
spectrodensitometer. The research results show that five samples of special color
inks were tested for compliance with customer standards. It was found that only
sample 1 and sample 5 did not meet the density standards at the Y value. However,
for the CIE Lab* values, all samples met the standards except for sample 4, which
was a special violet color.

Seiring dengan kemajuan teknologi, inovasi dalam formulasi tinta terus
berkembang untuk memenuhi tuntutan pasar yang semakin kompleks. PT DIC
Graphics merupakan perusahaan bahan kimia terkemuka dalam industri tinta cetak
dan memiliki beberapa implant di perusahaan percetakan, salah satunya di PT
Prokemas Adhikari Kreasi yang bergerak di bidang percetakan corrugated boxes.
Penelitian ini memfokuskan pada identifikasi masalah yang meliputi belum
diketahuinya nilai viskositas, density, dan CIE L*a*b* pada tinta hasil formulasi.
Rumusan masalah dan tujuan penelitian diarahkan untuk mengatasi masalah
ketidaksesuaian warna hasil cetak dengan standar yang diinginkan oleh customer.
Penelitian ini dilakukan teknik pengumpulan data dengan metode observasi, studi
kepustakaan, wawancara dan pengujian. Observasi dilakukan di Implant DIC PT
Prokemas Adhikari Kreasi, sedangkan studi kepustakaan melibatkan berbagai
sumber referensi ilmiah. Pengujian dilakukan dengan membuat formula tinta sesuai
standar customer, diikuti dengan pengujian viskositas menggunakan zahn cup 4,
serta pengujian density dan nilai CIE L*a*b* menggunakan spectrodensitometer.
Hasil penelitian menunjukkan bahwa lima sampel tinta warna khusus telah diuji
kesesuaiannya dengan standar customer. Dengan demikian, diketahui hanya sampel
1 dan sampel 5 yang tidak memenuhi standar density pada nilai Y. Sedangkan,
untuk nilai CIE L*a*b* pada seluruh sampel memenuhi standar kecuali sampel 4
warna khusus violet.
