part of the reading.\nA stripe measuring 3 mm on the left, 4 mm in the center, and 5 mm on the\nright is very different from a straight 4 mm stripe across the roller,\neven though the average is almost the same.<\/p>\n<div class=\"wl-table\"><table>\n<thead>\n<tr class=\"header\">\n<th>What the Stripe Looks Like<\/th>\n<th>First Place to Look<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr

id=\"if-the-whole-stripe-is-too-wide\">If the Whole Stripe Is Too\nWide<\/h3>\n<p>When the left, center, and right are all wider than the specified\nrange, the change is affecting most of the nip rather than one isolated\narea. Check the measurement condition first. A cold press and a fully\nwarmed press can give different stripe widths even when the adjustment\nhas not been touched.<\/p>\n<p>Once temperature has been ruled out, look at the setting and the\nroller itself. A larger effective diameter puts the two surfaces farther\ninto contact at the same mechanical position. A cover that has softened\nor swollen also deforms more easily and can produce a wider stripe.<\/p>\n<p>A wide stripe by itself does not tell you that ink transfer is\nbetter. If the machine manual calls for a narrower contact at that\nposition, increasing the stripe simply moves the roller farther away\nfrom its intended setting.<\/p>\n<h3 id=\"if-the-whole-stripe-is-too-narrow\">If the Whole Stripe Is Too\nNarrow<\/h3>\n<p>A stripe that gradually becomes narrower over months of service is\nworth comparing with roller diameter and cover condition. Normal wear\nremoves rubber from the surface. Aging, heat, ink, and wash chemistry\ncan also change the way the cover deforms under contact.<\/p>\n<p>The timing helps narrow the check. If a roller that used to run\ncorrectly becomes narrower little by little, wear or cover aging moves\nhigher on the list. If the stripe becomes narrow immediately after\ngrinding or replacement, measure the finished roller before adding more\nadjustment.<\/p>\n<p>The same narrow stripe can come from different combinations of\ndiameter, hardness, and setting. Measure the variables that can be\nmeasured instead of trying to judge hardness or roller condition from\nstripe width alone.<\/p>\n<h3 id=\"if-one-side-is-wider-than-the-other\">If One Side Is Wider Than\nthe Other<\/h3>\n<p>A wedge-shaped stripe is a strong left-to-right contact signal. Make\nthe normal adjustment allowed by the press and watch how both ends\nrespond.<\/p>\n<p>If both sides return to the specified range and remain stable, the\nsetting was part of the problem. If the wedge quickly returns, one end\nalready needs much more adjustment than the other, or the pattern\nappeared after bearing or roller work, check the mechanical condition\nbefore adjusting farther.<\/p>\n<p>Confirm that both journals are seated correctly. Look for bearing\nplay or mounting differences, and measure both ends of the roller when\ntaper or uneven wear is suspected. Do not rely on a single diameter\ntaken at the center when the stripe already shows a clear cross-width\ndifference.<\/p>\n<p>Similar cross-face contact issues also matter on <a\nhref=\"https:\/\/wolorin.com\/es\/function\/pressure-rollers\/\">Rodillos de presi\u00f3n<\/a>, where stable pressure distribution depends on the roller\nprofile, mounting, cover condition, and actual nip.<\/p>\n<h3 id=\"if-the-center-is-wider-than-the-edges\">If the Center Is Wider\nThan the Edges<\/h3>\n<p>A center-heavy stripe calls for a profile check. Find out whether the\nroller is supposed to be cylindrical or whether a crown is built into\nthe design.<\/p>\n<p>Crown is intentional on some printing rollers. Heidelberg SM\/CD 102\ndocumentation, for example, identifies its water pan roller as a crowned\nrubber roller. A center-wide contact on a roller like this has to be\ncompared with the specified geometry before anyone decides that the\nsurface should be ground flatter.<\/p>\n<p>If an old roller worked normally for a long time and the center\nstripe has slowly become heavier, compare the center diameter with both\nedges. Look at the wear pattern, swelling, previous grinding history,\nand the mating roller.<\/p>\n<p>If the pattern appeared immediately after grinding, check the\nfinished profile against the drawing. Grinding until the stripe simply\nlooks equal across the width can remove a crown that was supposed to\nremain on the roller.<\/p>\n<h3 id=\"if-the-stripe-breaks-in-the-same-area\">If the Stripe Breaks in\nthe Same Area<\/h3>\n<p>Start with the surface before treating a broken stripe as a geometry\nproblem. Clean the roller and the mating surface, then repeat the test\nunder the same condition.<\/p>\n<p>Dried ink, polished glaze, hardened deposits, a small dent, or\ndamaged rubber can interrupt the visible stripe. If cleaning removes the\ngap and it stays gone, keep monitoring the surface rather than sending\nthe roller straight to grinding.<\/p>\n<p>If the same section keeps returning at the same axial position,\ninspect that area more closely. Check local diameter, surface hardness\nif practical, glazing, indentation, wear, and visible damage.<\/p>\n<p>On an ink-transfer position, a polished or damaged band may also\nchange wetting, pickup, and release before there is a large measurable\nloss in diameter. Related contact requirements are covered on <a\nhref=\"https:\/\/wolorin.com\/es\/function\/transfer-rollers\/\">Rodillos de transferencia<\/a>.<\/p>\n\n<h2 id=\"compare-the-stripe-at-the-right-temperature\">Compare the Stripe\nat the Right Temperature<\/h2>\n<p>The target should come from the manual for the exact press and roller\nposition. There is no single stripe width that can be used as a general\nsetting for every offset press.<\/p>\n<p>A Heidelberg SM\/CD 102 manual shows why. Its table uses different\nvalues and tolerances for different contacts, including 4 \u00b1 0.5 mm, 5 \u00b1\n1 mm, 4 \u00b1 1 mm, and position-specific one-sided tolerances. The values\nbelong to those roller relationships on that machine; they are useful as\nan example of how position-specific the setting can be, not as a general\noffset standard.<\/p>\n<p>The same manual states that its listed stripe settings refer to\ninking and dampening rollers at working temperature. For a contact\nspecified at 4 \u00b1 0.5 mm, it gives 3.5 mm as the cold-setting example\nbecause the contact area grows as the rollers warm up.<\/p>\n<p>This makes temperature part of the measurement record. A 4 mm stripe\ntaken just after startup and a 4 mm stripe measured after a long\nproduction run were not obtained under the same condition. When checking\nan adjustment or a replacement roller, compare readings taken at similar\ntemperatures whenever possible.<\/p>\n<\/div><\/article>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1d8728a elementor-widget elementor-widget-html\" data-id=\"1d8728a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<style>\n.wl-a11{font-family:Inter,Arial,sans-serif;color:#2f3f50;font-size:16px;line-height:1.72;background:#fff}.wl-a11 *{box-sizing:border-box}.wl-a11 .wl-wrap{max-width:1180px;margin:0 auto;padding:58px 42px}.wl-a11 h1,.wl-a11 h2,.wl-a11 h3{color:#153a63;margin:0 0 20px;line-height:1.16}.wl-a11 h1{font-size:42px;font-weight:700}.wl-a11 h2{font-size:32px;font-weight:700;padding-top:8px}.wl-a11 h2+*{margin-top:0}.wl-a11 h3{font-size:22px;font-weight:700;margin-top:34px}.wl-a11 p{margin:0 0 18px}.wl-a11 ul,.wl-a11 ol{margin:0 0 22px;padding-left:24px}.wl-a11 li{margin:7px 0}.wl-a11 a{color:#1565c0;text-decoration:none}.wl-a11 a:hover{color:#f4b938}.wl-a11 strong{font-weight:700;color:#243c55}.wl-a11 .wl-table{overflow-x:auto;margin:26px 0 30px;border:1px solid #dde5ec;border-radius:10px}.wl-a11 table{width:100%;border-collapse:collapse;min-width:680px}.wl-a11 th{background:#153a63;color:#fff;font-weight:700;text-align:left}.wl-a11 th,.wl-a11 td{padding:13px 15px;border:1px solid #dde5ec;vertical-align:top}.wl-a11 tbody tr:nth-child(even){background:#f7f9fb}.wl-a11 blockquote{margin:24px 0;padding:18px 22px;border-left:4px solid #f4b938;background:#f6f8fa}.wl-a11 pre{white-space:pre-wrap;background:#153a63;color:#fff;padding:22px;border-radius:10px;overflow:auto}.wl-a11 code{font-family:ui-monospace,SFMono-Regular,Menlo,monospace}.wl-a11 .wl-hero{display:grid;grid-template-columns:minmax(0,1.25fr) minmax(320px,.75fr);gap:42px;align-items:center;background:#f5f7f9}.wl-a11 .wl-hero-media{background:#fff;border:1px solid #dde5ec;border-radius:12px;padding:14px}.wl-a11 .wl-hero img{width:100%;aspect-ratio:4\/3;object-fit:cover;border-radius:8px;display:block}.wl-a11 .wl-section{border-top:1px solid #edf1f4}.wl-a11 .wl-section h2:not(:first-child){margin-top:58px;padding-top:42px;border-top:1px solid #edf1f4}.wl-a11 .wl-cta{background:#f4f6f8}.wl-a11 .wl-actions{display:flex;flex-wrap:wrap;gap:14px;margin-top:26px}.wl-a11 .wl-btn{display:inline-flex;align-items:center;justify-content:center;padding:13px 22px;border-radius:6px;background:#f4b938;color:#153a63!important;font-weight:700}.wl-a11 .wl-btn:nth-child(even){background:#fff;border:1px solid #cfd9e3}.wl-a11 .wl-btn:hover{background:#153a63;color:#fff!important}\n@media(max-width:767px){.wl-a11 .wl-wrap{padding:38px 22px}.wl-a11 .wl-hero{grid-template-columns:1fr}.wl-a11 h1{font-size:33px}.wl-a11 h2{font-size:27px}.wl-a11 h3{font-size:21px}.wl-a11 .wl-hero-media{order:2}.wl-a11 .wl-section h2:not(:first-child){margin-top:42px;padding-top:32px}}\n<\/style><article class=\"wl-a11\"><div class=\"wl-wrap wl-section\"><h2\nid=\"check-the-roller-itself-when-the-stripe-changes-after-maintenance\">Check\nthe Roller Itself When the Stripe Changes After Maintenance<\/h2>\n<p>A stripe that changes immediately after grinding, roller replacement,\nbearing work, or remounting gives you a useful starting point. Check\nwhat changed during that work before compensating with more machine\nadjustment.<\/p>\n<p>Finished diameter comes first. Grinding removes material. A new cover\nestablishes a new outside diameter. Swelling can increase effective\ndiameter during service. If a new or freshly ground roller needs much\nmore adjustment than the previous roller to reach the same specified\nstripe, confirm the finished diameter.<\/p>\n<p>Then look at the profile. A roller can have the correct center\ndiameter and still be tapered, edge-worn, crowned incorrectly, or ground\nto the wrong cross-width profile. Where the stripe varies across the\nface, a few diameter readings across the roller are more useful than one\nmeasurement in the middle.<\/p>\n<p>Hardness is another part of the contact. A softer cover deforms more\nunder the same mechanical condition; an aged or hardened cover responds\ndifferently. Use the original hardness specification and an actual\nmeasurement when they are available. Do not try to calculate Shore A\nfrom the stripe.<\/p>\n<p>If the existing printing roller is specified as nitrile, keep the\nrubber specification together with the ink, cleaner, temperature, and\nservice history when preparing a replacement. The <a\nhref=\"https:\/\/wolorin.com\/es\/material\/nbr-rubber-rollers\/\">Rodillos de caucho NBR\/nitrilo<\/a> page gives the broader material background for\nnitrile-covered industrial rollers.<\/p>\n<p>Installation deserves the same attention. A roller with the correct\ndiameter and hardness can still leave a wedge-shaped stripe if one\njournal is not seated correctly, the mounting position changed during\nmaintenance, or bearing condition affects the roller position.<\/p>\n<p>For printing roller replacement or custom manufacturing, <a\nhref=\"https:\/\/wolorin.com\/es\/applications\/printing-industry-rollers\/\">Rodillos para la industria de la impresi\u00f3n<\/a> provides the broader context for matching diameter,\nhardness, surface condition, contact media, and finished geometry to the\nactual roller position.<\/p>\n\n<h2 id=\"when-regrinding-is-worth-considering\">When Regrinding Is Worth\nConsidering<\/h2>\n<p>Regrinding works best when the problem has been measured and the\nsurface or profile is still correctable.
