The SC inks eliminate the costly pre-processing step, whilst sharpening the quality of printed content to offset standards! It\u2019s the breakthrough moment that commercial sheetfed offset printers have been waiting for.<\/p>\n<p>For sheetfed printers, it does require a migration in technology to web-fed digital printing &#8211; something that raises a lot of questions around the production process and the finishing.<\/p>\n<p>In this blog we\u2019ll highlight the core differences in more detail.<\/p>\n<p>&nbsp;<\/p>\n<h4><span style=\"font-size: medium;\"><b>What\u2019s the difference between reelfed and sheetfed printing? <\/b><\/span><\/h4>\n<p>As we all know, paper is manufactured in large rolls. The core difference between sheetfed and reelfed printing comes down to the way this paper is loaded into the printer.*<\/p>\n<ul>\n<li>In sheetfed, the paper is purchased sheeted in packs or pallets before printing.<\/li>\n<li>Contrastingly, reelfed printing uses a large roll which is then cut into appropriate sizing in the <i><b>post<\/b><\/i> press process.<\/li>\n<\/ul>\n<p align=\"center\"><span style=\"color: #ffffff;\"><u><b>Confused about the difference between offset and digital printing presses?<\/b><\/u><\/span><\/p>\n<p>Describing it like this makes it look like a minor difference, but as you will soon find out, printing with reelfed has some pretty major implications \u2013 all positive.<\/p>\n<p>&nbsp;<\/p>\n<h4><b>The input side of reelfed:<\/b><\/h4>\n<ol>\n<li><b>It\u2019s cheaper: <\/b>it\u2019s cheaper to purchase a reel than it is individual sheets. Why? Because the paper manufacturer avoids having to sheet it. You only have to check with your supplier to realise this can easily save around 10% in costs for standard offset coated paper \u2013 bingo!<\/li>\n<li><b>It\u2019s less wasteful: <\/b>a reelfed production line makes it possible to eliminate printing gaps. This helps to use the paper most efficiently and can significantly reduce waste.<\/li>\n<li><b>It\u2019s easy to load: <\/b>Surprisingly, feeding paper into a reelfed inkjet printer is relatively simple compared to sheetfed loading. Instead of loading a pallet of paper, you would hang the paper in a so-called unwinder \u2013 an easy-enough process. Depending on the paper weight, the length on a reel can vary somewhere between 7km equating to 11,784 A2 Sheets on 250gsm stock and a whopping 18km, equivalent to 30,303 A2 sheets at 70gsm.<\/li>\n<\/ol>\n<p>&nbsp;<\/p>\n<p>Once in the printer, paper transportation is hassle-free. Unlike sheetfed, which relies on grippers and suckers, reelfed just consists of rollers and motors to control speed and paper path tension, as well as a device to keep the path precisely positioned under the printheads with sensors to monitor optimum stability.<\/p>\n<p>To sum up, reelfed paper transportation is much less mechanical and more stable than sheetfed. This makes for a virtually hassle and maintenance-free process.<\/p>\n<p>&nbsp;<\/p>\n<h4><b>The output side of reelfed:<\/b><\/h4>\n<p>Output happens using a rewinder or an inline finishing device. Several years ago, the majority of printing operators chose to run the finishing offline. We\u2019re now tending to see a change in behaviour, with inline becoming the preferred method as finishing technology grows ever more flexible and efficient.<\/p>\n<p>More often than not, inline finishing from printed reel to finished product is a big question mark for sheetfed printers. Ultimately it\u2019s in making the decision from sheetfed to reelfed, however, that the most efficiency is gained and here\u2019s why.<\/p>\n<ul>\n<li>A physical collating step is completely removed, because your products are collated digitally. The easiest way to explain this is by using these examples:\n<ul>\n<li><b>4 Colour Book:<\/b> With sheetfed offset printing, all the book signatures will need to be printed before finishing can start. The printing of a 6-signature book will mean 6 print runs on the press, using 12 x 4 plates (48 Plates in total) and producing 6 pallets of paper. After that signatures need to be to be folded in a first step and collated in a second step, and both are extra touch points in production.<\/li>\n<li><b>4 Colour 16pp A4 Brochure:<\/b> With sheet offset printing, again all the pages will need to be printed before finishing can start. The printing of a 16pp A4 Brochure using a SRA2 standard offetset press will mean 4 print runs, using 8 x 4 Plates (16 Plates in total), Section 1; 8 pages print front and then turn sheet to print reverse and then Section 2: 8 pages repeating process. Within off-line finishing, both sections will need to be pre-folded before passing through a stitch and trim line.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li>Producing digitally from the roll does not require plates or setup time and the signatures are collated digitally per individual copy on the fly. Withinfinishing the pre-collated sets will be cut to sheets, folded and stacked to complete the bookblocks. No touch points \u2013 no risk \u2013 no over-production; increased profitability<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><b>Reelfed Speed Comparison<\/b><\/p>\n<p>When it comes to reelfed the terminology is different. Sheetfed is monitored in the number of sheets per hour through the press whilst reelfed is calculated at number of metres of material per minute.<\/p>\n<p>It is often difficult to quickly calculate the difference and this often makes reelfed look slow in comparison with sheetfed, however this is not the case, reelfed is often faster than sheetfed.<\/p>\n<p>Now add in the benefit of in-line finishing and it is demonstrated that reelfed is superior to sheetfed in all \u201cpaginated\u201d production.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Productivity (duplex sheets)<\/p>\n<table
