Abstract

Industri percetakan saat ini masih sangat bergantung pada pengecekan warna secara manual yang rentan terhadap kesalahan manusia dan memakan waktu. Oleh karena itu, diperlukan suatu sistem yang mampu melakukan pengecekan warna secara cepat, akurat, dan objektif. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem pengecekan warna berbasis sensor TCS3200 pada mesin cetak flexo. Metode yang digunakan meliputi kalibrasi sensor, pengumpulan data warna standar, pengembangan algoritma pengolahan citra untuk ekstraksi fitur warna, dan perbandingan antara nilai warna hasil pengukuran sensor dengan nilai warna standar. Teori utama yang mendasari penelitian ini adalah prinsip kerja sensor warna, pengolahan citra digital, dan sistem kontrol. Hasil penelitian menunjukkan bahwa sensor TCS3200 mampu mendeteksi warna dengan tingkat akurasi tinggi (deviasi rata-rata Euclidean distance < 6) pada jarak optimal 2 cm dari objek. Sistem ini mengurangi ketergantungan pada pengecekan manual dengan konsistensi mencapai 86% untuk warna biru dan 82% untuk warna putih berdasarkan evaluasi operator. Konklusi dari penelitian ini adalah sistem pengecekan warna otomatis berbasis sensor TCS3200 dapat menjadi solusi yang efektif untuk meningkatkan kualitas dan efisiensi proses produksi pada industri percetakan flexo. Sistem ini dapat diaplikasikan pada berbagai jenis mesin cetak flexo dan dapat dikembangkan lebih lanjut dengan integrasi ke dalam sistem kontrol mesin yang lebih kompleks. / The printing industry still heavily relies on manual color checking, which is prone to human error and time-consuming. Therefore, an automated system capable of performing fast, accurate, and objective color verification is essential. This study aims to design and implement a TCS3200 color sensor-based system for flexographic printing machines. The methodology includes sensor calibration, standard color data collection, development of image processing algorithms for color feature extraction, and comparison between sensor-measured color values and standard references. The research is grounded in color sensor principles, digital image processing, and control systems. Results demonstrate that the TCS3200 sensor achieves high color detection accuracy (average Euclidean deviation < 6) at an optimal distance of 2 cm. The system reduces reliance on manual checks, showing 86% consistency for blue and 82% for white in operator evaluations. In conclusion, this automated color-checking system proves to be an effective solution for enhancing quality and production efficiency in flexo printing. It is adaptable to various flexo machines and can be further developed through integration with advanced control systems.
