1.Quantitative

Zviitiko zvinowanzoitika uremu, uremu hwepepa pane unit nzvimbo, inoratidzwa mugiramu pamamita mita. Kazhinji, hwaro huremu hwave pasi pe250 g / m2, iro rinonzi pepa; Huremu hwehushe riri pamusoro pe250 g / m2, iro rinonzi kadhibhodi kana pepa. Nhamba inonyanya kukosha yemuviri zviratidzo zvepepa, iyo nhanho kwayo uye kufanana kwayo, ichikanganisa zvese zvemuviri uye kuputika pepa kuita.

2. Kuzeza uye kusimba

Kukona kunoratidza℃rebepa rakakora, rinoreva gobvu repepa kana kadhibhodi mukuyerwa kwakananga kwekumanikidzwa pakati pemapuranga maviri ekuyera, muMM kana μm. Kazhinji, ukobvu hwekuchinja kwakananga pane opacity yepepa, hukuru hwakakura hwepaopi pane zviri nani. Kufanana kwatakarukwa kunonyanya kukosha kune pepa, kusagadzikana mukukora kunobata kuderedzwa kwegwenzi uye kuchena, uye toni uye ruvara kubereka kusimba.

Kusimba kunoreva uremu hwepapepa unit vhoriyamu, anozivikanwawo sehuremu, rinoverengwa nekukamuraniswa kwakaverengerwa.

Kusimbisa chiitiko chemuviri weiyo density yeiyo pepa chimiro, iyo imwe yepepa fiber bepa, iyo yakakura kusimba, iyo pepa racho zvakanyanya, pane zvinopesana, iro bepa rakasununguka. Kusimba kwepepa kunoenderana nesimba resimba.

3. Simba reCendele uye Elongation

Simba reChillile ndiyo yakanyanya kudhirowa iyo inogona kusimbiswa neyevhiringidza isati yadambura yeyunivhesiti yeyunivhesiti kana kadhibhodhi pasi pemamiriro ezvinhu akataurwa neyakajairika bvunzo nzira. Pepa parinotambanudzwa nekunetsana, pepa richatambanudzwa munzira yekumanikidza. Kana iyo yekudhonza ikawedzera zvekuti spline inobviswa, kugutsikana kunosvika pamugumo. Panguva ino, huwandu hwerefu hwekureba kusvika pakureba kwehurefu hunonzi leongation, rinoratidzwa sepesenti.

Zvokudhinda webhusaiti, kusimba kwesimba uye kusimba kwepepa chiratidzo chakakosha. Nekuti pepa rinotenderera muRotary Press, iro bepa richange riri pasi pekunetsana kukuru. Kana simba rakafanana nesimba rakaderera, rinokonzera bepa rakatyoka; Uye kana ma elongation yakakura kwazvo, ichachinja saizi yepepa kuti iwane kukanganisa kwakanyanya. Naizvozvo, kushandiswa kwepepa kune yakakwirira yeStentile Simba simba uye nekushomeka kwederera kunogona kudzivirira nekuderedza chiitiko chekupwanya pepa panguva yekudhinda, uye kuderedza kukanganisa kupfuura.

4. Kutsungirira kupukuta

Pepa kupukuta kutsungirira rinoreva kune yakatarwa bvunzo mamiriro, mumidziyo yakakosha, sampuli inogona kupetwa isati yatyora huwandu hwenguva, inoratidzwa mukuputika kaviri.

Kupokana kupokana ndechimwe chezvakakosha zviratidzo zvechinesheni simba repepa uye pepa. Icho chiyero chakazara chesimba uye kushanduka kwepepa. Iyi indekisi inodikanwa kune rakapetwa bepa uye bhodhi, asi mapepanhau, mapepa ekuvhara, zvekushandisa zvinonyanya kukosha kupetwa, kuti atore hupenyu hwayo, iwe unofanirwa kuti vade kuti vave nehuwandu hwakanyanya hwekupeta.

5. Pepa Pasi Simba

Simba rekumusoro repepa rinoreva pamusoro pemapepa emapepa, mafirita, pigment, etc. yakasanganiswa nepepa rakasimba, iro rinoreva simba repepa repamhepo rakasanganiswa nemumwe.

Muzhinji, Simba rewsprint Simba rakadzika kwazvo, nepo jira rakarongedzwa pamusoro pekusimba rakakwira. Kazhinji anooneka mune yekudhinda poda kubva pane chimwe chinhu chekurasikirwa kwebvudzi uye pamusoro pepepa zvine hukama zvakanyanya nehukuru hwekukura. Mukudhinda kwepepanhau, pamusoro pepepa kunowanzosvitswa neink firimu uye kusiira pane zvigadzirwa zvekudhinda.

6.smothness

Iyo- inonzi smoothness, pasi peimwe℃recuum, nehoriyamu yemhepo, nekumudzvinyirira kwemugwagwa uri pasi penzvimbo yepasi pevhu uye nguva inodiwa, inotaurwa mumasekondi.

Iko kusimba kwemusoro kwepepa kune zvakananga kukanganisa pakudhinda. Pepa racho riinhi nekukasira kusekerera kuri nyore kufukidzwa neiyo ink firimu, iyo yekudhinda yepepa rakachekwa riri nani pane iro repepa rekubvisa. Yakakwirira kwazvo kusimba kwepepa, kuti uwane mamwe maitiro ekudhinda wokudhinda, kugadzirwa kwemhando yepamusoro yekudhinda. Isu tiri kukumbira pepa nekuseka, teverwa neakakwira {} kupora pepa. Iyo unit yekunyora ndiyo mhepo inoyerera nguva. Iyo bvunzo yeyedzo ndeyekushandisa huwandu hwakatemerwa hwekumanikidza kwemhepo pamusoro pepepa nezve nzvimbo yekwere inch yepepa kuti uverenge iyo yekuyerera kwemhepo pasi pevhu. Nguva refu, iyo yakakwira kutsvedza.

7. Kuwanikwa

Iyo yekubira yepepa rinoreva kugona kwepepa rekutora mvura kana sol sol. Iyo ink iri pane ink yekunyudza yekugona, inogona kutaurwa kuti inki pane kugona kwepepa kuti ipinde. Hazvina basa chete neakasununguka uye capillary mamiriro epepa, asi zvakare zvine chekuita nezvinhu zvemapepa fiber, zvirimo zvecheki, kuumbwa nehunhu hwe inki, uye zvakare zvine chekuita nenzira yekudhinda uye nekudhinda kwekudhinda uye kumanikidza kwekudhinda.

Pepa rinoda kuve rakabvumikisa kusimudzira iyo Inki kuendesa. Nekudaro, kana iyo yekubika yakanyanya, iyo ink inosungirirwa mukati mepepa zvakawandisa, uye zvinokonzeresa kuumba girazi, zvichikonzera kushaikwa kwechigadzirwa chakadhindwa uye kunyangwe kudhinda kweiyo ink layer. Kazhinji, iyo yakakura kusakura, iyo yakajeka yekuwedzera network network, apo iyo yekushatisa yakanyanya kusimba, asi zvakare inotungamira mukudhinda kwekudhinda ink, kukanganisa zvakanyanya kunaka kwezvinhu zvakadhindwa.

8. Whiteess

White Whiteness zvinoreva kune iyo℃rekuchena kwepepa ndiko kuwanda kwekuratidzira kwechiedza chinooneka mune ese wavelength kuratidzwa yunifomu. Izvo zvinhu zvikuru zvinokonzeresa kuchena ndiro zviripo zvemukati uye℃rakasarudzika mupepa remapepa. Nekuda kweiyo yero maitiro ekuruva, zvinodikanwa kuti uderedze zvirimo mupepa kuti uwane iyo pepa neyekuchengeterwa kuchena.

Kuchena kwepepa kune simba rakakura pane ruvara renji reiyo yekupedzisira yakadhindwa chigadzirwa. Iyo yakakwira chena yepepa, iyo inonyanya kujairika ruvara rwe inki iri. Iyo yakawanda yakajeka ruvara rwechigadzirwa chakadhindwa ndechekuti, iyo yakafara ruvara rwejut ndeye. Iyo chena yepepuru yepepuru inowanzo kuderera, yero, uye chena yepafosita pepa uye pepa rakachekwa rakakura.

9. Opacity

Iyi ficha inoreva mazwi nemifananidzo yakadhindwa kune rimwe divi repepa, nepo rumwe rutivi ruchadhindwa nerugwaro kana mifananidzo, havazoratidzika phenomenson. Opacity yakanaka yepepa yakakwira, zvekuti yakagadzirwa nebhuku kuitira kuti vaverengi vafunge kuverenga zviri mukati me peji, hazvizotyamwiswa pamativi ese emhedzisiro yekuita kuti maziso arege kuneta. Zvinhu zvinokanganisa opacity ndezvekuti: Ini. Ukobvu hwepepa yacho pacharo; ii) kungave kana kuti glue yaiswa; III. Kutsika uye kuomarara kwepepa pamusoro; iv. Iyo nzira yekuedzwa ndeyekuyera kuti yakawanda sei mwenje unopinda pepa iro, iyo unit ndiyo chikamu muzana.

10. Grossess

Gloss ndeyemapepu yemapepa mune yekudzokorora chiitiko chechiedza uye yakazara girazi rekuwedzera nepepa pane imwe kona yegirazi

Pepa menderekedzo dzinowanzo kuyera huwandu hwechiedza chinoratidzwa kubva pamusoro pepepa chena uye muzana yerentance. Iyo indasitiri ichashandisa iyi chiyero kuti giredhi iro bepa, iyo yakanyanya huwandu hwepepa yemhando yepamusoro yemhando yakapedza chigadzirwa. Pepa rakaburitswa, ruvara rwekudhinda runoratidzika kunge rwakajeka. Mamwe mapepa nemagazini anoshandisa yakakwira

Kubva pane zviri pamusoro apa, zvinogona kuoneka kuti zvinhu zvepepa zvine chekuita nekudhindwa kwepepa, izvo zvinozivikanwa kune vese vekudhinda. Nekudaro, huwandu hwekukanganisa kukuru pakudhinda uye kubereka, huwandu uye hukuru hwehukama pakati pekudhinda uye kubereka asi havasi vese vanoziva. Kana huwandu hwekuita kwekudhinda hwekudhinda hunogona kuve hwakaitwa neyakafanirwa kurondedzera saizi, saka indasitiri yekudhinda kuti itungamirire kugadzirwa kwacho pasina rubatsiro rukuru.
