APAKAH MAKSUD DANDY ROLL dalam CORSICA?
Watermark
Tanda air adalah imej atau corak yang dapat dikenali di dalam kertas yang muncul sebagai pelbagai warna kegelapan / kegelapan apabila dilihat dengan cahaya yang ditransmisikan, disebabkan oleh ketebalan atau variasi ketumpatan dalam kertas. Tanda-tanda air telah digunakan pada setem pos, mata wang, dan dokumen kerajaan yang lain untuk menghalang pemalsuan. Terdapat dua cara utama untuk menghasilkan tanda air dalam kertas; proses roll dandy, dan proses acuan silinder yang lebih kompleks. Tanda air berbeza-beza dalam penglihatan mereka; manakala ada yang jelas pada pemeriksaan kasual, yang lain memerlukan beberapa kajian untuk dipilih. Pelbagai bantuan telah dibangunkan, seperti cecair air yang merapikan kertas tanpa merosakkannya. Tanda air sering digunakan sebagai ciri keselamatan wang kertas, pasport, setem pos, dan dokumen lain untuk mencegah pemalsuan. Watermark sangat berguna dalam pemeriksaan kertas kerana ia boleh digunakan untuk temu janji, mengenal pasti saiz, cap dagang dan lokasi kilang, dan menentukan kualiti kertas. Pengecekan kod pengenalpastian ke dalam muzik, video, gambar, atau fail yang didigitalkan dikenali sebagai watermark digital.
