Dakwat inkjet industri: memilih gred yang sesuai untuk barisan anda

Daripada katalog pembekal hampir tiada apa yang boleh disimpulkan tentang pemilihan dakwat, tetapi satu kelompok di barisan sudah cukup menjelaskan. Penentunya ialah substrat, persekitaran dan proses selepas cetak.Lihat substrat dahulu, kemudian apa yang berlaku selepas cetakSoalan pertama dalam memilih dakwat bukan nombor model, tetapi dicetak pada apa. Filem plastik, logam, kaca, kotak kadbod, sarung kabel: keperluan lekatan semuanya berbeza. Dakwat yang sama kering elok pada filem PE, tetapi pada PP atau bahagian acuan yang masih ada sisa agen pelepas boleh terkelupas dengan jari. Lebih menentukan ialah proses selepas cetak. Sama ada produk melalui air, masuk bilik sejuk, bergesel semasa disusun, atau disapu dengan alkohol — soalan ini menapis dakwat lebih tepat daripada substrat itu sendiri. Kami pernah melihat barisan yang percetakannya sempurna tetapi runtuh pada peringkat pempasteuran atau penyejukan. Persekitaran kilang juga perlu dikira. Jika suhu melebihi tiga puluh darjah sepanjang tahun, dakwat cepat meruap dan kepala cetak berkulit; di kawasan sejuk atau lembap, kecairan pada suhu rendah dan kepantasan kering menjadi penting. Catat keadaan ini lebih awal, julat pilihan terus mengecil separuh.Mengapa nisbah pelarut sentiasa tersasarDalam sistem CIJ, dakwat dicairkan dengan pelarut untuk mengekalkan kelikatan; berapa banyak diisi dan berapa kerap memberi kesan langsung pada kualiti cetakan. Kebanyakan mesin ada pengisian automatik, tetapi ia mengisi isi padu, bukan nisbah tepat. Apabila suhu dan kelembapan berubah, kadar penyejatan berubah, dan kepekatan sebenar tersasar dari nilai yang ditetapkan. Cara paling langsung mengesan sisihan ialah mengukur kelikatan dan melihat cetakan. Jika tepi garisan kabur dan muncul titik satelit, kelikatan biasanya tinggi. Jika cetakan pucat dan lambat kering, mungkin terlalu cair. Daripada menunggu amaran, catat satu bacaan setiap syif bersama suhu dan kelembapan; selepas beberapa catatan corak kilang anda akan kelihatan. Dan pelarut mesti dari sumber yang sama dengan dakwat. Nisbah setiap pengeluar tidak boleh ditukar ganti: mencampur tidak kelihatan pada mulanya, tetapi lama-kelamaan membentuk enapan yang sukar dibersihkan pada muncung dan saluran, dan kos pembersihan jauh melebihi penjimatan pembelian.Spesifikasi sebenar ialah ketekalan kelompokBagi dakwat, bacaan cantik daripada satu botol tidak bermakna jika berbeza antara kelompok. Warna, taburan saiz zarah dan kekonduksian: jika mana-mana satu daripada tiga ini berayun antara kelompok, tingkah laku pada barisan berubah. Bagi pengilang pembungkusan, yang paling teruk ialah warna keluar berbeza dalam pesanan yang sama. Sebab itu semasa memesan, minta pembekal menyertakan rekod pemeriksaan kelompok bersama penghantaran, sekurang-kurangnya bagi tiga perkara ini. Rekod itu bukan formaliti, tetapi asas yang boleh dijejaki: apabila masalah sebenar berlaku, kelompok dan tempohnya dapat dikenal pasti serta-merta. Jika ada kemampuan, kelompok baharu sebaiknya dicetak sampel dahulu sebelum masuk barisan dan dibandingkan dengan yang sedang digunakan. Jika perbezaan warna kelihatan mata, jangan masukkan seluruh kelompok. Pemeriksaan ini mengambil sedikit masa dan lebih murah daripada kerja semula.Penyimpanan, jangka hayat dan botol yang dibukaDakwat dan pelarut mempunyai jangka hayat, dan ia dinyatakan untuk bekas tertutup. Selepas dibuka, kiraannya berubah. Di kilang lazimnya botol terbuka diletak di rak selama setengah tahun, kemudian digunakan apabila sudah luput. Cara betul ialah catat tarikh buka pada botol itu sendiri, kira semula tempoh dari tarikh tersebut, dan guna mengikut prinsip masuk dahulu keluar dahulu. Suhu simpanan dikekalkan dalam julat munasabah, elak cahaya matahari langsung dan sumber haba. Pelarut khususnya perlu kedap: bekas terbuka bukan sahaja kehilangan isi padu tetapi juga menyerap lembapan sehingga menjejaskan prestasi. Dan stok diselaraskan dengan kadar penggunaan sebenar. Dakwat tidak menjadi lebih baik dengan menimbun lebih banyak: ia mengikat modal dan menghampiri tarikh luput. Stok dua hingga tiga bulan dengan masa penghantaran yang stabil lebih munasabah daripada pembelian besar sekali gus. Sementara itu, logik pembelian dakwat, pelarut dan cip adalah sama: item kecil, ditambah secara berkala, dan berisiko gangguan bekalan. Menggabungkannya dalam satu senarai alat ganti dan merancang secara suku tahunan, sambil memesan bahan guna habis serasi untuk platform biasa termasuk VJ dan DM, menjimatkan banyak masa penyelarasan. Di TOPMARK kami menguruskan item ini bersama, dan pelanggan melengkapkan keperluan suku dengan satu pesanan — lebih stabil daripada penambahan berasingan.Senarai pendek sebelum memesanKesimpulannya. Pastikan substrat dan proses susulan serasi; dakwat dan pelarut dari sumber sama; pembekal memberi rekod pemeriksaan kelompok; tarikh buka dicatat dan penggunaan mengikut masuk dahulu keluar dahulu; serta stok berada dalam dua hingga tiga bulan yang munasabah. Lima perkara, tiada yang rumit, tetapi setiap satu berdiri di atas masalah sebenar pada barisan. Yang diperlukan dalam pemilihan bukan gred dengan data paling cantik, tetapi gred yang berjalan stabil pada pengeluaran anda.
